Mark Perry seems to have missed a good story.
He's been talking recently about how the income share of the top 20 percent has been FLAT since 1994, as shown here.
What's more interesting, however, is the oddity that his charts show that the income share of the top 20 percent experienced a pronounced spike up between 1992 and 1994, which includes the first two years of the Bill Clinton administration.
Why did the richer get a bigger share of the income pie after Bill Clinton raised taxes on them in 1993?
Top marginal income tax rates had declined from 38.5 percent in 1987 to 28 percent in 1988, as shown here, and in 1991 another higher rate of 31 percent was added under Bush 41. But under Clinton in 1993 an additional marginal rate of 39.6 percent was added with the help of the Democrat controlled Congress. So higher marginal income tax rates prevailed, but the richer nevertheless got a bigger share of the income.
That doesn't make any sense. How did that happen?
The answer is Clinton's middle class tax increases.
For one thing, the cap on income subject to Social Security taxes was raised. That bumped up the limit on incomes on which the tax was levied. A tax increase for all wage earners. For another thing, the cap on income subject to Medicare taxes was removed. That meant no ordinary income could escape the tax any longer. Another huge tax increase. And thirdly, Social Security income beyond 50 percent up to 85 percent became subject to income taxation. Anyone taking Social Security income felt this, not just the rich. Another huge tax increase.
These were massive tax increases on wage earners, as opposed to those richer Americans who could take their income differently if need be, often in the form of capital gains, or from tax-free municipal bonds, or from tax shelters.
The net effect of the Clinton tax increase was that just about everyone in the four quintiles below the top 20 percent lost ground on income, which meant that the rich appeared to spike up in their share of the income pie. The regimentation in law of the tax increases on everyone altered and froze the aggregate shares of the income pie going forward, hence the flatness of those charts since 1994.
The truth was that Clinton's tax increase on the richer, who ended up shifting income to avoid taxation, masked a massive tax increase on everyone else, who couldn't shift their income if they wanted to, and they've experienced a smaller bite of the income pie ever since.
That's what expanding the tax base in tandem with raising rates will do.
Republicans, take note.
