Debt allows you to leverage yourself. Why would you want to keep 100% equity in your house if you could borrow the equity for 5% and make a guaranteed 7%?. So, everyone who borrowed funds from Japan and invested it in higher yielding markets (carry trade) are slaves just because they have "debt?" Not all debt is bad.
I researched that case (the foreclosure case cited in the film). The attorney was the defendant who claimed the mortgage note lacked consideration, and who initially won the case. He was apparently disbarred (temporarily) for bringing a frivolous claim (attacking the monetary structure of the U.S. Government), and the Judge who agreed with him died while the case was on appeal.
