First you gotta get a cool super power, like invisibility or something. Then you go around pick pocketing rich people. Only do this if your super power is invisibility, otherwise they may be able to see you! After a while, put your loot in the washer (it's called money laundering). Then go on eBay or the farmer's market or something and sell the stuff back to the rich people. They won't know it's theirs because of the laundering (it smells different now). You will be rich in no time! Good luck, friend.
