Have you ever wondered why some economies keep surging forward while others stall, even when they seem to have all the ingredients for success? I’ve been thinking about this a lot lately, especially after diving deep into the ideas of one of the latest Nobel Prize winners in economics. His core message is surprisingly straightforward yet profound: real, lasting GDP growth doesn’t come from protecting what already exists—it comes from constantly allowing the new to challenge and replace the old.

In a recent conversation that really stuck with me, this economist laid out how creative destruction—that relentless process where fresh talents, ideas, and companies push aside yesterday’s leaders—fuels long-term prosperity. It’s not always comfortable. It creates winners and losers. But without it, economies stagnate, innovation dries up, and everyone ends up poorer in the long run. Let’s unpack what he had to say and why it matters right now.

The Power Behind Sustained Economic Growth

At its heart, the theory boils down to this: growth happens when new innovations emerge, capture market share, and force everyone else to either adapt or fade away. It’s a cycle. Talented people get the chance to enter markets, build something valuable, and earn rewards. But those same successful players can’t be allowed to lock the door behind them. If they do—through monopolies, collusion, or cozy government ties—the whole system grinds to a halt.

I find this perspective refreshing because it flips the usual debate. Instead of arguing over how much government should spend or tax, the focus shifts to whether markets stay open enough for disruption. When they do, growth follows. When they don’t, you get complacency and decline. Simple, but powerful.

Why Competition Is the Secret Sauce

Competition isn’t just about lower prices at the checkout. It’s the pressure that keeps incumbents on their toes. Without it, yesterday’s winners rest on their laurels, using their power to block newcomers rather than innovate further. The economist pointed out that strong competition policy is essential to prevent this. It ensures that markets remain contestable—new entrants can challenge the giants without facing insurmountable barriers.

Think about it. In a truly dynamic economy, even the biggest players know someone hungrier could show up tomorrow with a better idea. That fear drives continuous improvement. Remove that threat, and you get stagnation dressed up as stability.

  • Encourages entry of new talents and firms
  • Forces existing players to keep innovating
  • Prevents rent-seeking and market lock-in
  • Drives productivity gains across the board

Of course, getting the balance right matters. Too much regulation can scare off startups just as effectively as monopolies do. But the evidence suggests many economies lean too far toward protecting incumbents these days.

The Rising Threat of Protectionism

Protectionism is making a comeback—tariffs, subsidies for national champions, and all sorts of barriers. While they might feel good in the short term, they shrink the playing field. Smaller markets mean less incentive to innovate big. Fewer rivals mean less pressure to improve. And technology transfer between countries slows down, hurting developing economies most.

I’ve always believed free trade, done sensibly, amplifies growth. It rewards the best ideas wherever they come from. When countries close borders or favor local giants, they risk turning inward and losing the spark that drives progress. The economist was blunt: this trend is bad news for long-term prosperity.

Trade barriers hamper innovation. Free trade gives you a bigger market for your innovations, which means bigger profits, as well as more pressure from competition.

That resonates. We’ve seen how open markets lifted billions out of poverty in recent decades. Closing them now would reverse hard-won gains.

Big Tech Dominance and the AI Horizon

Then there’s the issue of today’s tech giants. In the late 1990s and early 2000s, companies harnessing IT really turbocharged growth. They knew how to use the tools better than anyone. But over time, unchecked mergers and weak antitrust enforcement let them consolidate power. New entrants struggle. Productivity growth slowed after the mid-2000s, and many link it to this concentration.

Now AI looms large. It holds massive potential. Yet dominance in cloud computing, data, and chips could limit who gets to play. The worry is real: if a handful of firms control the infrastructure, they might stifle the next wave of breakthroughs. Aggressive but smart competition policy—perhaps forcing data sharing or blocking harmful mergers—could keep the field open.

Personally, I’m optimistic about AI’s upside. It could automate routine tasks while unleashing human creativity in new directions. But only if the ecosystem stays competitive. Otherwise, we risk repeating the IT slowdown on a larger scale.

Handling the Losers in Creative Destruction

Here’s the tough part: disruption hurts. Jobs disappear. Industries shrink. Entire communities feel the pain. Ignoring that reality breeds resentment and political backlash. So how do we make the process more humane?

One approach that stands out is a flexible labor market paired with strong support for those displaced. Think generous unemployment benefits, active retraining programs, and help finding new roles. This “flexicurity” model—seen in places like Denmark—lets creative destruction run while cushioning the blow. People feel safe enough to take risks, and the economy stays nimble.

  1. Keep labor markets flexible for quick adjustment
  2. Provide substantial temporary income support
  3. Invest heavily in retraining and upskilling
  4. Encourage rapid re-employment

AI will displace some roles—especially repetitive administrative ones—but it will create others too. Better education systems, from basic literacy to advanced skills like calculus, prepare people to adapt and thrive. In my view, skimping on education is the biggest self-inflicted wound an economy can make.

AI’s Potential Boost to Productivity

Recent estimates suggest AI could lift productivity by roughly 0.7% per year if we measure only task automation. That’s solid—comparable to the digital wave of the late 1990s—but probably understates the full effect. AI excels at recombining existing knowledge into novel ideas, sparking entirely new innovations. That second-order effect could push gains higher.

The catch? If incumbents choke off competition, the boost shrinks dramatically. Optimism about technology needs to be matched with realism about institutions. History shows societies adapt slowly to big shifts. We can hope for the best, but policy has to actively clear the path.

Avoiding the Middle-Income Trap

Many countries reach a decent level of development, then plateau. They master imitation—copying advanced technologies—and grow fast. But eventually, the low-hanging fruit disappears. To keep going, they must shift to frontier innovation: creating new knowledge, not just adopting it.

That transition is hard. During catch-up, big firms or conglomerates often dominate. They lobby against reforms that would foster competition and entrepreneurship, fearing it threatens their position. Several Asian economies have struggled with this. Large players block smaller rivals, slowing overall progress.

The lesson is clear: institutions must evolve. Pro-competition policies, strong IP protection without overreach, and support for new entrants become critical once imitation runs dry.

Europe’s Competitiveness Challenge

Europe caught up impressively after World War II, but the gap with the US has widened again since the mid-1990s. The single market remains incomplete—especially in services—limiting competition. Many firms focus on incremental tweaks rather than bold disruption.

Venture capital lags behind America’s ecosystem. Long-term research funding is insufficient. Europe excels at science in some areas but struggles to turn ideas into global companies. A more pro-competition industrial policy—modeled on successful public-private efforts elsewhere—could help.

Greater collaboration across borders, including with neighboring countries outside the bloc, would enlarge markets and intensify rivalry. Completing the single market and building a true innovation ecosystem feel like low-hanging fruit waiting to be picked.

What About the UK’s Productivity Puzzle?

The UK has battled sluggish productivity for years. Leaving the single market reduced competition and shrank effective market size, hurting incentives to innovate. Closer cooperation with European partners—in defense, energy, health—could reverse some damage. Implementing pro-competition reforms and boosting investment in frontier research would help too.

It’s not hopeless. With the right moves, the UK could reignite dynamism. But it requires political will to prioritize long-term growth over short-term protection.


Looking back over these ideas, one thing stands out: growth isn’t automatic. It demands constant vigilance to keep markets open, support those displaced, invest in people, and resist the temptation to shield incumbents. Creative destruction may sound harsh, but it’s the engine that has lifted living standards dramatically over the past two centuries. Taming its downsides while preserving its power is perhaps the central economic challenge of our time.

What do you think—have we leaned too far toward protection lately? Or is there a sweet spot we’re missing? I’d love to hear your take.
