I, OTOH, am not as circumspect as Ravenman. He is surely the better man for that, but I can’t help but noticing that, long before we get to the 2001 tax cuts, we run into the sort of bullshit that we routinely chop to bits on this board when a poster presents it.
Take the very first table, “Lower tax rates in the 1920s meant more tax revenue.” Two things strike me about it: (1) the surge of tax revenues in 1927 and 1928 - could that have just possibly been due to all the fortunes people were making in the bubblicious stock market of the late 1920s?
This should have been a familiar issue in 2001, because it was certainly argued at the time that Clinton’s surpluses were at least partly due to the stock market bubble of the late 1990s.
- Isn’t 1928 a rather interesting time to cut that graph off? Wonder what it would show if it were extended a few more years? Might that not deflate the thesis somewhat?
Gotta wonder about that with respect to Table 2 as well.
With Table 3, there’s just a two-year increase in the rate of growth subsequent to lowering the top tax rate from 90% to 70%, then it apparently goes back to what it had been before the Kennedy tax cut. Maybe there’s more there, but I don’t see it.
In the text, they say that inflation-adjusted tax revenues increased by 1/3 from 1961 to 1968. AFAICT, they’re actually understating their case - in the (warning: big-ass PDF) U.S. Budget Historical Tables, Table 1.3, it shows an increase of 38.3%. Fine, but how does that compare with other 7-year periods in the postwar era? I looked at the other years ending in 1 and 8 as a subsample, since looking at all 50+ periods would be a pain:
1951-58: 17.0%
1961-68: 38.3%
1971-78: 28.2%
1981-88: 14.7%
1991-98: 39.8%
2001-08: 10.4% (projected)
No substantial tax cuts in the odd decades, and substantial tax cuts on the high end in the even decades. And what happens? The odd decades win! 1990s > 1960s, 1970s and 1950s > 1980s and 2000s. My, my.
Maybe it looks better in a comparison amongst all 7-year periods, but they provide no yardstick: just “here’s the tax cut, here’s the rate of increase in tax revenues, ergo.”
