This is sad. Listen to the audience applaud as Bernie Sanders promotes one socialist program after another.
Bill Maher tries to counteract Sanders, but he has no skill in knowing how to advance free market ideas. He seems to have no idea that he can use arguments that show Sanders' programs will create great government-controlled central power operations that will lead to inefficiencies, distorted price production signals, wipeout incentives to advance health science and result in a government controlled system that is ripe for corruption.
Maher is correct that Sanders' proposals will be extremely expensive, but that is only the start of the problem.
