Years ago, it wouldn't have been that hard. I can rent a Rolls or a yacht for a day, half-day or an hour. Capitalism is relatively new in human history. Prior to capitalism, the way people amassed great wealth was by looting, plundering and enslaving their fellow man. Capitalism made it possible to become wealthy by serving your fellow man.
Capitalists seek to find what people want and produce and market it as efficiently as possible.
They've already saved lives and made us healthier. Despite the miracles of capitalism, it doesn't do well in popularity polls. One of the reasons is that capitalism is always evaluated against the non-existent utopias of socialism or communism. Any earthly system pales in comparison to utopias. But for the ordinary person, capitalism, with all of its warts, is superior to any system yet devised to deal with our everyday needs and desires.
