“Republicans are patriots, they love their families,” allowed Barack Obama, “but they are operating on a theory that time and again has proven to be wrong.” What theory would that be? “[I]f we just reward folks at the top, everybody else will do just fine.” In truth, here’s the difference: Conservatives believe that money belongs to the person who earned it. We’re not “rewarding” anybody by letting them keep the fruits of their own labor. Leftists believe that what a person earns belongs to someone else – namely, the government, which can then redistribute it to favored constituent groups. Who’s theory, exactly, has proven to be wrong?
