Go back and read any U.S. history book, and see what life was like for the "middle class" throughout most of this country's history.
I don't recall the Ingalls family buying lots of horses or going on any vacations in Little House on the Prairie. The reality is that life was harsh for most people back then -- and "home ownership" was largely nonexistent until the U.S. government started giving land away to settlers (that's right -- another big-government socialist program).
Before the 1950s, most of the "middle class" in our urban areas lived in homes that they rented from someone else.
