When did I say anything like that? My point is that an illegal foreclosure sure seems like one way that a wealthy institution could force a family into economic hardship. And it has happened thousands and thousands of times in recent years and the result in those cases is that a bank was able to directly extract wealth from less powerful individuals with impunity. So there is one example of a way that wealth can flow upwards when it shouldn't be.
Okay . . . and illegal foreclosure is . . . get this . . . illegal. There are also people in the "lower" and middle classes who rob, burglarize, and murder the wealthy. Your example does nothing to prove that on a widescale basis one entire group was prohibiting another group from being able to thrive (which is what twofingers was asking for, and which in your response implied that you were providing that proof).
