If you needed another reason to put a priority on income inequality, here is one.
A new paper from a trio of Boston College researchers shows that the states with the highest degree of income inequality are also the worst offenders for carbon emissions; as the share of wealth and income claimed by the richest 10% increases, the amount of carbon-intensive consumption they engage in grows, as does their political clout, allowing them to buy laws and policies that let them pollute more.
Democrats should stand for getting rid of all regressive taxes and replacing them with a steeply progressive income tax, the opposite of what Republicans are busy doing right now.
