Poor people have been proven to have less molecules. The reason a poor person is no different in size to someone who is wealthy is that their molecules are bigger, their physical size is probably not much different than Gunther Gebel-Williams, CEO of Walmart, who is said to contain over 3.7*10^982612 much more tiny molecules. Although these "simple" folk can't think as fast due to having such simple minds, they recieve great government discounts on medical services because they are so easy to fix.
