There is a small problem -- more innovative society next door will get richer and eat you anyway. So lets enjoy the good times and be weak men while it lasts.
Let them get richer, the same people who talk with these threatening remarks also talk how capitalism isn't a zero-sum game, someone else becoming richer doesn't mean someone else getting poorer, right? Just means getting richer at a slower rate, Europe is pretty rich on global standards, let's keep getting a bit richer while others get the chance to reach these levels.
That would be, in my opinion, an orthogonal issue, and not clear from your "and eat you anyway" remark.
The only good thing coming out of both Trump's terms is the diminishing influence of the US, I can see your point on how US money could influence politics here but at the same time it's also now much harder for that influence to take hold properly. US influence was much stronger back in the late 90s, early 00s, it's been waning since 9/11, and kinda reaching a tipping point with Trump.
The next financial implosion, which is inevitable in the boom-bust cycles, can likely cement this diminished influence, the US won't have that much extra money sloshing around to fuck with other countries, they are losing long-time allies which propped them up to recover from the 2008 mess they created. It'll probably be the best time to decouple away from the US, including their financial influence in our politics.
