Why Liberals Like Taxing The Wealthy

I have long been puzzled by the enthusiasm with which many young liberal bloggers cheer on proposals to raise tax rates on high earners. I can understand why they might favor them, but not why they seem to invest so much psychic energy in the issue.

Some of this may just be team ball: You cheer when your side puts up numbers on the scoreboard. So Democratic cheerleaders are rah-rahing what they insist on calling repeal of the Bush tax cuts (which have been in effect now longer than the Clinton tax increases they rolled back).

But the liberal bloggers cannot be entirely ignorant of the knowledge that we have a pretty progressive income tax already. In 2009, the top 1 percent of earners reported 17 percent of adjusted gross income and paid 37 percent of total income tax revenues.

By some measures, the American tax system, including the payroll tax and state and local taxes, is more progressive — in the sense of extracting disproportionate shares of revenue from high earners — than most European tax regimes, which rely heaving on value-added taxes.

Plus, as liberal economist Lane Kenworthy points out, you don’t get much income redistribution from higher tax rates.
