For all its many faults the US seems to have realized a long time ago that you cannot protect incumbents at the cost of startups.I think it wasn't an American realization as much as it was a success of "the American experiment" 250 years ago, a European experiment undertaken by Europeans living in North America, taking European ideas from the Enlightenment and applying them broadly, to politics, to religion, to the economy, and it flourished.
The tendency to protect incumbents was harder to root out back where the incumbents were more firmly entrenched.
If you want to take the "loose analogy" approach even further, consider that the Enlightenment was also the integration of Northern European ideas stemming from individual self reliance because you need to when it's cold as fuck outside, as opposed to southern European/Roman Empire successful ideas of depending on huge bureaucracies to gather and apportion more abundant resources.
this is not a proof of anything, just a pointing out/noticing type set of ideas. To me it seems tied in to other intellectual trends we see in history, where the , e.g., Romantic era was a movement in music, and in art, and in literature, and in politics/social theory, seemingly unrelated areas moving in concert, a reflection of how our brains work.
(probably similar ideas can be found outside the West, but it's not something I'm that educated about)
