the poor get poorer and the rich get richer for a pretty simple reason- the rich lend the poor money so that they can live beyond their means for a little while- and then the poor pay interest on the debt for the rest of their lives giving the rich more of their money. well that and how the information age has made everyone more efficient- these advantages are used much better by the top of the top, so naturally they are able to distance themselves a bit more from everyone else.
the great thing about america though- is that it is possible to become one of those top 1%. several of the richest people in the world didn't come from wealth cradle to grave, but got there themselves. that is what the american dream really is. who cares what the gap between rich and poor is when you can be born into poverty and die shitting on a golden toilet. there aren't many places in the world with that kind of economic freedom, and it is just plain impossible to do in communist or socialist countries where becoming wealthy is impossible because they fear the gap.
i love the gap, i just hope i can close it and get into that top 1%.
