Democrats vs Republicans

It isn't like the democrats aren't obligated to lobbyists too!

I was watching an interview with some MIT professor who was talking about reciprocal altruism ( Wikipedia) which is hardwired into our brains as part of our biological evolution. "Do Unto Others as You Would Have Them Do Unto You" or "Tit for Tat" is as much unconscious as religious. Every time you give any gift, you expect an equal value or better one back and if this doesn't happen, you feel taken advantage of - watch anyone at a bar who buys his buddy or a woman drinks. It is one thing to use your own money to try and keep things equal, but incredibly easier if you use public money.
