This a beautiful display of "1%er" tone deafness and ignorance of reality, like Mitt Romney's advice that people should simply borrow money from their parents if they want to go to college and start a business.
FWIW, I’ll be lucky not to be homeless when I retire.
The general advice is to have at least, what, a million saved for retirement. 15 is a lot, not so much that it’s unreasonable to my mind for a successful person.
