Hum, I don't know how the system works in the US, but in France a lot of money is taken from the salary to cover for health insurance, unemployment insurance and retirement plan. Plus we have 5 weeks paid vacation automatically included.
And I think cost of life is lower than in the US, even in Paris which is the more expensive area.
To go with numbers, I currently earn 50k€ per year (gross), which makes for 3k€ per month (net). I don't have a car (no need in Paris). This income is enough for me to live my life without any privation, going to bars, cinema, restaurant, weekend trips, etc whenever I want, and still save 10 to 40% of it each month. Last year I bought a new computer, a new phone, and 2 weeks vacation in Iceland without even touching my savings account.
All that knowing that if I go unemployed, I stay at full pay several months, if I'm sick I'm covered, and when I reach 65 yo I'll get retirement rent until end of life. Oh, and I'm only in my early 30's, meaning I get to get paid more and more.
After my next raise, which should occur this year considering I got a title upgrade, I'm even considering stopping asking for money and asking for additionnal time off instead.
So, I don't know how your 100k+$ reflect on your life in the US, but sorry I don't feel any need for it :)
