You misread me, my ruminating friend. I’m a fairly libertarian type and a fierce deficit hawk, in truth. But for years my job has been reading electorates and trying to predict their demands and behaviors before they do it. It’s like Ouija Board reading without the little tear-shaped thing.
As for challenging your numbers, above, I was challenging your assumption that the pattern of taxation as a percentage of GDP was a result of your defined ‘negative feedback loop’. In fact, my back-of-the-envelope shows little of that. In fact, even if taxes as a percentage of GDP went down, overall government income from taxation went up considerably!
In 1947 the federal government took in (from the link you provided) approximately $38 billion. By 1961 it took in $94 billion. In fact, here’s a small chart:
Tax %Change GDP %change
1945 $45B $221.4B
1963 $106B 135% $599.2B 170%
So you’re correct that GDP growth outstripped government revenue growth. But it’s not like that should be a bad thing, is it? With the highest marginal rates in American history we find that, over time, the economy is keeping a higher percentage of its production. It seems counter-intuitive to me, somehow.
% of taxation of GDP
1945 20.3%
1963 17.6%
So, while your thesis is correct that revenues as a percentage of GDP declined over time (Note: I was initially going to use 1947 - 1961 but saw that Ruminator had stated 1945 - 1963 so changed up.) I’m having trouble seeing that as a bad thing. The economy as a whole prospered, kept more of itself to itself (that is, in companies, individuals, and so forth) and government revenues increased 135% over the time period in question. In fact again:
If we calculate inflation based on the Consumer Price Index we find this:
1945 CPI 18.0
1963 CPI 30.6
For a percent change of 70%. That’s a lot of inflation, don’t get me wrong, but it’s still way behind tax receipts and GDP growth.
% change
Tax Receipts 135%
GDP 170%
Inflation (CPI) 70%
A clear win for the American economy as a whole, even with high marginal rates of taxation.
In short, your overall assertion that altering the highest marginal rate is somehow a downer for receipts and GDP is not born out by evidence during the times in which such were highest. There’s a lot of noise in the data, for example I would have liked, as I mentioned, to start later than 1945 to try to screen out the last year of WWII but I thought I should stick with the years you introduced into the discussion in fairness.
As for the whole demagoguery of ‘soaking the rich’ that you introduced there it is, simply untrue. Even with current top marginal rates going back to levels seen in the Clinton era that only means and increase of about 3% or so on the top level. Hardly a ‘soaking the rich’ vein when it still leaves that top marginal rate, as demonstrated in one of my earlier posts, far below other developed, first world countries.
I am also not, in any way, advocating a return of 90% top marginal rates. But I do think that higher rates across the board (remember my job, up in that first paragraph) will be both necessary and acceptable to the electorate in the near- and middle-term. A higher top marginal rate of 45% could easily be passed and accepted if presented properly. Hell, that would still be a lower top rate that for the majority of Ronald Reagan’s Presidency. If I’m reading the chart properly we’re looking at:
1982-1986 50%
1988 28%
1990-1992 31%
1994-2000 40%
2002 39%
2004-2008 35%
2010 40% (proposed)
So for most of the great communicator’s administration we found the highest rate to be 25% higher than the proposed rate for 2010 and beyond. I don’t think we’ll find much in the way of revolutionary fervor downstream at this level and even several points higher.
Whew! That was a lot of research for a Saturday night! And I don’t even drink. Well, not anymore, anyway.
