"Any conservative admits to the legitimate role of social and economic justice and of the enforcement of high ethical standards in the way business is conducted. They will also admit to the necessity for government involvement in these areas. Justice is in fact at the center of free market economic models and no one would say that laws covering how business is conducted is out of place."

You haven't met the same conservatives I have.  They say that government must not interfere in "the market."  They also believe that capitalism is completely removed from social justice and that its only mission is return on investment.
