I can see how it sounds pretentious, but it's somewhat true. After you have the limits of your financial investments explorable, you aren't just going to ignore the potentially soul destroying daily grind. You do it if it does something for you, and if you're basically rich, you might as put your energy in a different place.

But you're right, the 70k place might be just as much work, but they just don't make that much money, or any other series of situations.
