Good point, it's interesting to note the 2 people referenced in the article were fairly well off--I mean one was a manager at Microsoft.
The idea that you need financial success to do this though is a bit strange. I think it's easier to just quit your job when you're poor from an outside perspective because you're not giving up very much in terms of the grand scheme--you'd throw away a penny before you'd throw away a $20 bill right, but speaking from experience when you're poor, these shit jobs mean a whole helluva lot.
If you live cheaply, saving up a few thousand will allow you do things you'd like to pursue without worrying about money; if you have big house mortgage, fancy car, expensive wife, then giving up a luxury job suddenly becomes not so easy.
