Part of the benefit of living in the US is the relatively low tax climate (California notwithstanding, its state income taxes are 4x what I pay) which generally leads to increased socioeconomic mobility (a disputed statement, I know).<p>I imagine the advice for a European with a salary cap of approximately 70-80k is the same for an American with a salary cap of 85-90k: wealth is most likely only going to come from entrepreneurship or blind luck.
