Germany and London pay much less though but experienced developers can get decent wages.
Edit: also, when I lived in the u.s. and ma"de significantly more than 100K I still felt like I was scraping by. Taxes in the u.s., especially California, are high, expenses are high, and plus I had no time to spend my money anyway. If take a couple weeks off to travel every now and then but would have to at least answer emails while traveling. No more of that.
1) American workers don't work 60+ hours to earn 50% less than what people in Switzerland do.
2) The median income in the US is barely below that of Switzerland.
3) The average American worker does not work more than 45 hours per week for the median income.
4) If you compare people of a similar qualification + education + demographic, Americans earn more than people in Switzerland per hour worked, and have more disposable income thanks to a lower cost of living and lower taxes. The US has a very real poverty problem that is especially bad in the black community, and it substantially alters the stats on incomes / standard of living. The asian median household income for example is 100% higher than the median black household income.
I don't want this to get sidetracked to be a conversation about Switzerland though. In general life is better in Europe than the u.s. - less desperate. At least you have obamacare now.
Spain has 30% real unemployment. France's economy hasn't grown in ten years in inflation adjusted terms, and is suffering hyper stagnation; it has averaged sub 1% nominal GDP growth for that time. Italy is on its third recession in seven years. Portugal is so relatively poor their middle class would barely qualify as poor in the US. Greece is a total economic disaster still.
The Netherlands, Ireland, and Denmark are the three most indebted countries on earth per capita compared to income. Lavish spending today to fake prosperity, to be paid for tomorrow with lowered standards of living. The US has done plenty of that too, but it can more easily manage its debts than European nations can.
The total GDP of Europe is still below 2007 levels, and looks set to remain below that level for another ten years inflation adjusted. Pegging the European economy in effectively a 20 year depression.
Moldova, Latvia, Lithuania, Poland, Belarus, Russia, Romania, Ukraine, Macedonia, Kosovo, Bulgaria, Albania, Bosnia, Croatia, Czech, Slovakia - you're telling me life is more desperate in the US, than in these countries? That's blatantly false.
France just saw its unemployment rate hit new highs. The US unemployment rate is now almost half that of France.
In fact, the US unemployment rate is chasing back down toward that of Germany, and the US economy is growing faster than Germany's. And that's with a labor force participation rate higher than nearly all of Europe; ~7 points higher than France, ~3 points higher than Germany, ~10 points higher than Belgium etc.
With available labor being substantially reduced, wages are likely to begin climbing again in the US soon - you aren't going to see that in most of the countries of Europe, because their economies are not growing.
The private plans for the self-employed/underemployed do suck though. Eventually the country needs to dump the foolishness of employer-based private insurance into some more mature, rational, and responsible approach to universal healthcare, but for now it's sadly the best we could manage.
I'm not sure how other parts of Europe compare.
Many, many places that "starting salary" is more like $50-60k.
