You are ignoring that there is a second parameter: Willingness to be corrupted. I believe that there is extreme overlap between high personal wealth and a willingness to be corrupted, which would make richer people worse politicians. Everyone says "everyone has a price" but we have examples of normal people being given the opportunity to have way more power and giving it up for the greater good (for example, smedly butler who was supposed to become some sort of supreme leader in a fascist plot, but turned the conspirators in instead, and basically got no reward for doing so, and the conspirators largely went unpunished)
