Good article by Larry Beinhart at Huffpost:
Weird Tax Myths #2 - Recessions, Depressions and Tax Policy. Beinhart destroys the conventional wisdom that "Tax cuts stimulate the economy."
Our prevailing mythology is that tax cuts help the economy.
They stimulate it. They promote growth. They create jobs.
The truth is that tax cuts cause crashes.
Tax hikes end depressions and recessions.
Beinhart supports his thesis with historical examples:
But now that we've had four of them (including the crash of 2001), we can see a pattern.
The sequences of boom, bubble, and crash have, in each and every case, been preceded by a significant tax cut.
Coming out of World War One we had a top marginal tax rate over 70%.
From 1921-25 it was cut, in steps, down to 25%.
There was a boom, particularly in the fiscal sector.
The crash came in 1929.
When Ronald Reagan came into office in 1981, the top marginal rate was, once again, 70%.
Reagan started cutting in 1982, down to 50%, then to 38.5% in 1987, and 28% in 1988. There was a boom in the fiscal sector. In the mid-eighties the collapse began, and over 1,600 banks failed. There was a huge bailout.
It was followed by the recession of 1990.
There are more examples of tax increases and cuts and the resulting boom or bust:
The 2,000 recession was followed by tax cuts. Not tax hikes.
A very strange think followed. There was great growth at the top. Corporate profits rose, there was a boom in real estate and in the fiscal sector generally.
But for normal people the recession never ended. There were no new private sector jobs. Median income went down. Manufacturing continued to decline.
The historical record suggests that this recession won't end until there is a tax increase.

If the Bush tax cuts are allowed to expire they will, hopefully, work as tax hikes. That will mark the beginning of a real recovery.
If they don't, and there are no other tax increases, expect lingering unemployment, lower wages, increased corporate profits, especially in the fiscal sector -- which we're already seeing -- a short term boom in the stock market, and another crash.
Sorry about busting the 4 paragraph rule - but the paragraphs in this article were very short.
