Here in the US we basically have little or no social safety net, and certainly few meaningful regulations and laws protecting labor. Our "wow just wow" salaries have less buying power than yours, because any difference in the margins is eaten up by having to use the additional salary for basic services you would be able to (mostly) take for granted as being government supplied (via taxation and other means).
Mainly corrupt, well-connected private businesses who take a generous cut of the benefits the government contracts them to distribute, one way or another.
I'm not too sure about that. Yes, if you compare the average American to the average European, you make more and have to pay for more things, so it more or less evens out.
No, it doesn't really even out at all. There are several factors you're neglecting to consider here.
The salaries listed here are in our highest cost of living areas. The vast majority of developers aren't earning anywhere near these wages. Most are in the $50,000-$90,000 range (not too far off of your EUR$35k - $50k figures). Second, I think you're discounting far too heavily how much extra the average American has to contribute on his own for his own health and retirement. One might consider the 15%-20% one should take out of his pre-tax salary for savings to be an implicit tax we have to pay. The federal marginal rate for an individual earning $130k/yr is around 30% (for the sake of argument--it's actually a bit higher). In SF and NY, the state taxes wll boost that 8%-10% (or more). So the base tax rate is already around 40%. Couple that with this implicit tax, and Americans are paying a "tax" that is about what Europeans pay. Except we get a lot less for it by a long, long way. And, actually, since it's infreqent to earn that much money as a software developer without having a college degree, there is the additional factor of the cost of our education. Most people can't afford the 15%-20% hit to their pay because of the high cost of everything else, so the 'add-on' cost that hits them in retirement is even worse.
Well, a 50k salary will net you <30k€ in Germany (but more if you have kids). You probably should also save a bit for retirement, since you won't get much from the state (today's retired receive much more than they paid into the fund, but current generations will receive much less). Oh, and we have a 19% sales tax over here (7% on groceries, and food is actually very good and cheap in Germany, at least in stores).
I'm surprised by the (low) 50-90k salaries you mention. I've always read much higher numbers. Probably due to the bias on blogs/news sites to West Coast companies.
