One guy I'm close with, and we've talked about our salaries.
I make 200k My friend in Europe makes 30k.
The difference is astounding.
Also, if you take median salary in software industry, which is probably closer to $65k, in my country it buys you much better lifestyle than 200k in the Bay Area does. Me, for example, I was able to buy 2 bedroom, 900 sq ft apartment in the capital city with cash, no mortgage required. Other expenses don't really register on my radar. I'm piling up cash for early retirement.
EDIT: fixed some of my numbers.
EDIT2: After my country joined EU I never emigrated to Western Europe, because it didn't make financial sense to me. If I ever find myself emigrating to California, that would be because of the weather, not money.
And yes, there is this particular kind of people who feel offended by this. Largely the same people who get offended by gay marriage. Why should we care?
people might get offended because you are wrong.
