Lust: More funding for family planning, expanded access to contraception
Gluttony: Increases on the "sin taxes" levied on cigarettes and alcohol, imposition of a new "sin tax" on soda/sweetened beverages, reduction of subsidies to large farms and reallocation of agriculture spending to smaller farms engaging in sustainable agricultural practices, stricter control over marketing to children
Avarice: a more steeply progressive income tax scheme such as that of the 1950s, perhaps even a maximum income, a financial transaction tax such as that being implemented in the EU, stricter regulation of the financial industry
Sloth: a more steeply progressive inheritance tax
Wrath: Cuts to defense spending, an end to the drone war in Pakistan and Yemen, an end to the militarization of the CIA, an assault weapons ban, a ban on high-capacity magazines
Pride: Campaign finance reform
I can't think of an ideal fit for envy because its negative effects are primarily direct inward, and I see social democratic policies as more focused on curtailing the avarice of capitalism than eliminating envy.
Basically, if politics are to accomplish any good, there must be a strong foundation in morality.
