I would tend to believe that is true because people who are educated in business administration, accounting, etc, tend to have a more realistic view of economics than those who have no such training. Democrats are an accountants nightmare.
Without being able to examine the study that determined this, my guess would be that wealthy people in general have more college educated people among them and are the ones best able to afford college, and more wealthy people are conservative/Republican.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
