Alright, Keating.

I’m going to go out on a limb and guess that you, as an outspoken atheist, are a believer in Darwinian evolution (or some close variant).

Would you suggest that humans (or any other form of life) would have been better suited to survive and thrive had they been “intelligently designed” by a God or other central force?  If your answer is “Yes” then the reason you hold fiscally liberal ideals makes more sense to me.  If, however, your answer is “No,” then it begs the question of if Darwinian evolution works for creating the most adaptable, able species in any given environment, why would it not work to create the most adaptable, able entities in any given economy?  Of course, I liken capitalism to Darwinian evolution of companies and other enterprises.

Furthermore, should you state that you do believe humans came to be as a result of Darwinian evolution, it is not a far step to then state that humans are the result of evolution and we will act upon the basic instincts that have been instilled in us over billions of years that made us what we are today.  That is, humans are inherently greedy and selfish and will act on those instincts no matter what the economic structure of a society is.  As such, should we not aim for an economy that benefits from greed and selfishness rather than one that is debilitated by it?
