1. They have an axe to grind
2. As part of the elite, they feel that under socialism, they would be the in charge or rubbing elbows with those that are
3. They are wed or socialize with liberal men/women of like ilk
4. They have too much time on their hands and are constantly looking for causes which fill their lives
5. They’ve already made their wealth and can afford lawyers/Accountants that help them dodge their obligations
IMHO
“As part of the elite, they feel that under socialism, they would be the in charge or rubbing elbows with those that are”
The very crux of the issue. Being able to be part of the world of real power. Another reason Hollywood is so Socialist as well. They want to be more than actors and think that Obama will put them in charge of things.
Ironically I think they’ll be the first ones in front of the firing squad and their assets and children confiscated.
