In most of the EU, the US subsidizes your defense budget, too.
Do you really think that, if we spent more on our armies, you would spend less? Anyway, I'm not saying that our system is better - for example, here it's more difficult to find a job, and wages are usually lower enough (also because of the taxes necessary to finance the welfare state). What I was really thinking about is how much having to worry about medical expenses and retirement money changes the stress level in…
In the abstract sense, it'd also be curious to see what effect on those social benefits would result from a termination of the security guarantees which the US has extended to an ever broader fraction of Europe since 1949. I'm not so cruel a man as to actually wish such an outcome on anyone, but I certainly would like to see the people charged with the responsibility of governing my nation take an interest in the wellbeing of my nation, rather than investing so much expense and effort in defending an entire continent which can barely be moved even to a token expression of gratitude, much less any actual quid pro quo, in exchange for it.
As regards the remainder of your comment - yes, without social guarantees of medical care and a livable retirement, life is much more stressful than it would otherwise be, and this additional stress is inversely proportional to socioeconomic standing, with an exponential term in the function. Is this really such a novel thought as your comments here make it seem? I find it obvious beyond the point of triviality, but I suppose someone who's never actually lived with it might not previously have had cause to give it any consideration.
