The pittance we pay to support things that benefit all humanity have never prevented us from investing in the US.
You don't need to put the federal government in a wood chipper to make the US better, and in fact you often need the federal government to make the US better, like with social security, food stamps, medicaid, the interstate, railroads, most of our infrastructure, the internet, microchips, etc.
In fact, if you want the best infrastructure, why wouldn't you end up importing that? Most of humanity is not a US citizen. "The best" human at something will only rarely be american.
Meanwhile this admin has done nothing to improve things for americans, so stop carrying water for their horse shit.
People love the meme of a runway full of F35s and saying "We are about to demonstrate why the US doesn't have socialized medicine" and it has always been a lie. We can EASILY afford 3k F35s, 13 aircraft carriers, AND healthcare. We've been paying more for healthcare than countries with socialized medicine this whole time.
