If I had the power, would I do what the rich and famous do for their kids? Of course I would! My kid is incredibly bright, but he's had some setbacks. He's a foster youth who hasn't had an easy life. If anyone deserves someone to cheat on his behalf, he does.
We all feel that way about our kids. That they deserve another chance, that they caught some bad breaks, that their future is too important to be left to chance. Inequality enables some parents to act on those natural feelings to the detriment of other people's kids.
