I thought your high taxes pay for education and healthcare? How is that free?
Firstly, college is "free" but at the trade off of not everyone being able to go. Instead the government decides who gets to go. In USA anyone can go to college. It's not uncommon for people in their 30s and 40s in USA deciding to go to college. In Europe you have to perform well enough on exams very early in your life if you want free college, otherwise no college for you.
Secondly, I would argue Europe can spend so much on social services because the US buys so many aircraft carriers (and jets and bombs, etc). Post WW2, Europe's military is very weak and can't really project force at all (just look at how well Europe responded to muslim genocide happening next door 20 years ago). Without the US military presence in Europe, Russia would have annexed a bunch of eastern European states by now.
USA isn't perfect, but USA has unique problems that are hard to solve.
It is hard to imagine a European lifestyle as we know it today without the advantage of the US military being a deterrent to Russia/China and the latest wannabe dictator.
Please note, I am not blaming the Europeans here, just trying to be realistic and look at a bigger picture.
The real difference is that in general you get what you pay for, and most college education is just licensing.
US has cheap prices too (see: community colleges). Doesn't have the prestige factor of ultra expensive universities, but great if you are looking for education.
the F-35 program
I doubt the US as a monolith could pull those things off, the bigger the organization the worse it usually is at execution.
