Rich people are just like poor people in regards to concience and soul. Some rich people support Obama because their concience demands it. If you make a habit out of defying your concience you will never sleep at night. You will become ill and feel like crap on a daily basis. I've known this since I was a teenager. Your wealth doesn't dictate your concience. On the other hand rich people with a lack of a concience will support anyone and anything that pertains to them aquiring and keeping more wealth.
Poor people with a concience will still give you the shirt off of their back if you are in need. Whereas some poor people with a lack of concience will watch you bleed in the street and walk on by.
Only a very narrow minded person thinks that every action we take in life is based on the monetary consequences of that action. You can be the wealthiest person in the world and be very liberal in your ideology. Why does Warren Buffet continue to make the case of trying to be legally obliged to have less money at the end of the day? Because he has a concience whereas many of his fellow oligarchs do not.
