An economic viewpoint of the world is often an unrealistic one. Economists are taught in school that growth is infinite: the economy just has to keep growing for everything to proceed as normal. You know what's not infinite? Earth. And all the natural resources that need to be exploited for the economy to keep growing. Still I listened to Freakonomics Radio for a few years anyway, but stopped at their episode on "Why Rent Control Doesn't Work," where they advanced the argument that rent control "doesn't work" because it keeps wealthy property owners from kicking out their tenants, remodeling their buildings, and selling their properties at a greater profit... thus exacerbating gentrification. If profit for the wealthy at the expense of a hundred poor citizens is what you believe "works," then we have a fundamental difference of morals, and I'm through listening to Freakonomics Radio.
