A moderate libertarian? Wow, that's refreshing :)

More seriously, I think there is a strong case for seriously limiting if not completely eliminating government intervention in the economy as those interventions often lead to very unintended consequences, notably favoring special interest groups at the expense of others.

As Milton Friedman said: "One of the great mistakes is to judge policies and programs by their intentions rather than their results."

Regarding income inequality, I do think it is a worrying phenomenon but a very small price to pay for a healthy economy and most of all, individual liberty.
