Yes and no. It is very impressive what humans can do and the US is a remarkable country for managing to achieve what they have. On the other hand, if we're talking GDP it is basically just a trendline [0] of whether you let people better their own lives or not.

The main reason for US success on the GDP front is that the median administrator chooses to make people fail and the US does the best job of resisting that tendency. To me the mystery is less why the US succeeds but more why polities are so committed to failing. It isn't even like there is a political ideology that genuinely wants to make it hard to do business [1]. It mostly happens by accident, foolishness and ignorance.

I think you have one big piece of it: economic progress has a lot of search problems and it is impossible to master-plan it; consequently free intelligence beats centralized regulation. It's a bit out-dated now[0] but The Fifth Discipline distinguishes between 'detail complexity' (things that have a lot of bits you have to figure out) and 'dynamic complexity' (systems that have feedback loops and adaptive participants). It might simply be that handling systems with dynamic complexity is out of the reach of most humans. Economic regulation strikes me as something that can be particularly like a thing that modifies a dynamic system.

In fact, creating good policy in a modern economy might be so dynamically complex that no mind alive today can simultaneously comprehend an adaptive solution and act in such a way as to bring it about.

Perhaps, given this, we are simply spoiled by the effectiveness of certain economic actors (e.g. the Federal Reserve) in maintaining an monetary thermostat. Their success is not the norm so much as it is extraordinary.

Focusing on GDP handwaves away so much around externalities that it's hard to know where to start with it.

How much worse off would people be if the US GDP was 20% lower but FB/Instagram/Google/everybody-else weren't vacuuming up ad dollars by pushing as-addictive-as-possible mental-junk-food in people's faces to make them feel bad about themselves? How much of that GDP is giving anyone optimism for improving their own individual condition?

How much of the nostalgia for the olden days is about agency and independence and perceived trajectory vs purely material wealth (from a material standpoint, many people today have more and better stuff than boomers did as kids, when a single black and white TV may have been shared by a whole family)?

Would regulation preventing the heads of big-tech advertising firms from keeping as much of that profit for themselves really be a net drain? Some suggestions for that regulation, harkening back to US history:

1) bring back super-high marginal tax rates to re-encourage more deductions and spread of salaries vs concentration in the top CEOs and execs. worked for the booming 50s! preventing the already-powerful, already-well-off from having another avenue to purely focus on "better their own lives" seemed wise there. seems like there were mega-wealthy super-tycoons both before the "soak the rich" era in US history and after it, but fewer minted during it?

2) instead of pushing more and more people into overtime or second jobs, go the other way and revitalize the earlier 20th-century trends towards limited work hours. get rid of overtime-exempt classifications while at it. Preventing people from working 100 hours a week to "better their own lives" and preventing them from sending their kids to work as early to "better their own lives" seems to have worked out ok.

3) crack down on pollution, don't let people "better their own lives" by forcing others to breathe, eat, and walk through their shit

4) crack down on surveillance, don't let people "better their own lives" by monetizing the private lives of others; focus on letting others enjoy their own lives in peace instead

Every component here is ill-defined and doubtful, especially the claim that lower regulation is the "main" reason.
