Those who are born into wealth tend to be progressive and call themselves Democrats. Conservatives are usually the newly wealthy and fell they earned it given the roadblocks and other deterrents that the Old Wealth (the Progressive Democrats) have put in placed to avoid newly rich people from making it. Now the Conservatives may be self driven and may not understand why others are not. Having a welfare system is the way the Old Wealth keeps the impoverished from rioting and as a means of a base of power against the New Wealth and uses the New Wealth as a scapegoat to blame for the policies and outcomes of the Old Wealth. Also, Old Wealth doesn't have the same drive as the New Wealth so they would not think it odd that someone would not necessarily have the means to get out of poverty so again Old Wealth would lean progressive and be more likely become Democrat.
