I've seen you make this claim in other threads. Most rich people I know did it themselves. Most of them are third generation Americans whose ancestors came here dirt poor. They aren't billionaires but they are wealthy enough.
I remember you complaining that you couldn't get the type of work you think you deserve while people around you who were born rich had it easy. Maybe these rich people simply didn't share your attitude regarding what it means to work toward something.
Sorry to drag out an old quote, but this attitude seems prevalent these days, and it's not a good one. Many many jobs make some "greedy bastard" more money than you, that's kinda how it works, but eventually, if you work hard, you can become that greedy bastard. Or perhaps you can be not so greedy, but you have to earn it either way.
I don't blame you though in some ways - the economy and job availability situation is crap, no matter how politicians spin it and tell us otherwise. It is tougher to make a buck, and salaries have been stagnant for a long time.
As for the Clinton's, like many politicians, they seem to have somehow gotten rich by being politicians, which is a bit interesting given the salaries that we pay them.
