Wall Street Journal editorial, Where the Tax Money Is: Obama Targets the Middle Class While Pretending to Tax Only the Rich:

A dominant theme of President Obama’s budget speech last Wednesday was that our fiscal problems would vanish if only the wealthiest Americans were asked “to pay a little more.” … The mathematical reality is that in the absence of entitlement reform on the Paul Ryan model, Washington will need to soak the middle class—because that’s where the big money is. …

[I]n 2008, there was about $5.65 trillion in total taxable income from all individual taxpayers, and most of that came from middle income earners. The nearby chart shows the distribution, and the big hump in the center is where Democrats are inevitably headed for the same reason that Willie Sutton robbed banks.

This is politically risky, however, so Mr. Obama’s game has always been to pretend not to increase taxes for middle class voters while looking for sneaky ways to do it. His first budget in 2009 included a “climate revenues” section from the indirect carbon tax of cap and trade, which of course would be passed down to all consumers. Such Democratic luminaries as Nancy Pelosi have often chattered about a European-style value-added tax, or VAT, which from a liberal perspective has the virtue of applying to every level of production or service and therefore is largely hidden from the people who pay it.

Now that those two ideas have failed politically, Mr. Obama is turning as he did last week to limiting tax deductions and other “loopholes,” such as for mortgage interest payments. We support doing away with these distortions too, and so does Mr. Ryan, but in return for lower tax rates. Mr. Obama just wants the extra money, which he says will reduce the deficit but in practice will merely enable more spending.

Keep in mind that the most expensive tax deductions, in terms of lost tax revenue, go mainly to the middle class. These include the deductions for state and local tax payments (especially property taxes), mortgage interest, employer-sponsored health insurance, 401(k) contributions and charitable donations. The irony is that even as Mr. Obama says he merely wants the rich to pay a little bit more, his proposals would make the tax code less progressive than it is today.
