Ok, it's the first time i'll go into it here, and i'm probably not the best writer (especially in english), but this typical of the bourgeois mindset.
You don't have to have capital (social/economic or cultural) to have the bourgeois mindset. It two things in my opinion: either you're aware that your capital, your capital esperance, or your comfort is iniquitous and you're justifying this iniquity by any myth or legend you can invent, either you're not even aware of the iniquity and how your less fortunate peers are doing.
I've been thrice in the US. California, Ohio/West virginia, and New-York/Maryland. I've talked to people trying to get the tenderloin moving, i've talked to dockers and construction workers, and i've spent a lot of time with back-to landers but also "rednecks", ex-miners or truckers in WV. I guaranty you, a Polish trucker have a better life quality than a West Virginia one. And i would rather be a construction worker in europe, anywhere, even in Croatia, than in Maryland. At least i could hope to survive my 60s.
Our standard of living don't mean much. I mean, i go sail as a leisure almost every day, i'm 2 minutes away from the sea (by foot), i've got enough money to buy a house outside the city if i want to, my main issue this day is that i need to weld a support on my bike to be able to bring my kite board with me, as the best place to kite is 20 minutes away, and doing it by bike would be shorter.
Having more than 55k/yr at 30 wouldn't make me any happier. The new fablab and engineering "courses" i will try to make for the less fortunate kids of the city with 3 friends next year will probably though.
