Only if you're dumb enough to live like you're earning $633,000 a year. If you lived like you're earning $100K and put the rest into a savings account, you could quickly overcome all your financial worries.
I doubt anyone is that clever, though, especially if you're surrounded by other folks earning $633K and feel the need to keep up. Entire industries exist for the benefit of those who make $633K and can't think of any sensible way to spend it.
I don't see why you doubt that anyone who earns $600k is clever enough to live cheaply : Banks prefer to hire smart people...
But there's also an element of management preferring their employees to live at/above their means to some extent, just so they have to keep putting in the hours... (This is really true : I employ sales people in a trading room, and it's easy to see that they react to financial pressure by making more money).
