I'm not sure wealth is exactly the reason. My fiancee grew up... not poor, but definitely without money. She and her entire family are super conservative, gun-loving and all. The only liberal in the family is her sister, which can be best explained by her going to college to be a teacher. I, on the other hand, am from an upper-middle class family, and even educated w/ graduate degrees, but also super conservative. Most of the wealthier people around here are very liberal, and the more middle and lower class people tend to be conservative (this, of course, is generalizing and not always true. Plenty of wealthy conservatives, poor liberals, etc, too). Income is a factor, but character is more what's going to shape political ideology. Those who can't do anything for themselves, and never have had to, expecting someone else to essentially support them, are those that tend to be more progressive. They thrive on victimhood, and pointing out inequity in everything, and expect the government to be the great equalizer

Despite coming from a fairly well-off family, I made some bad choices in my early twenties, and was homeless for a while. It took some serious "pulling myself up by the bootstraps," to get my shit together, and I credit that experience with waking me up to the toxicity of progressive politics. It would have been far easier to cry "woe is me," and beg for the government to save me, but that's not how life works. I stopped doing drugs, got a job, finished school (then kept going back for more degrees because I'm a sucker for punishment apparently), met my fiancee, and kept building a life for myself. Tough to not be a conservative after that
