Remember this little saying, "the sins of the father are passed to the son to the third and forth generations." Old Joe Kennedy was a thief and all the booty he collected from his bootlegging days have brought nothing but disaster to his offspring and theirs.
Also, all the talk about paying your fair share of taxes by little scumbags like him just makes me crazy. All of these types of "old money" people who've put all of their money into "trusts", which pay the least in taxes, and family members never get paid much, on the books at least. Everything they have is owned by the trust and paid for by the trust, so they don't really need a paycheck.
