I’ve often wondered if Mark is doing his part by having the 3d or 4th child? In any case, his math is correct and we’re essentially screwed financially and much of that is do to demographics. Kotlikoff’s ‘The Coming Generational Storm’ is a superb book on the subject.
Even better Buchanan’s Book: “Death of the West”
You are right, we are headed the way of Greece...just wait until 76 million Baby Boomers are all on SS and Medicare, and everyone else is on Obamacare...WHO is going to pay for it???
