s-t-d: Your response here is quite unclear, because I'm having trouble following which rates you're talking about. You make a number of points, which I'll try to address. As I see it:
-- the FICA rate (not including Medicare) was 10.18% in 1980 and went up to 10.7% in 1981, 10.8% in 1982 and 1983, 11.4% in 1984-1987, 12.12% in 1988, and 12.4% in 1991. The income threshhold at which the FICA rate went to zero increased steadily over the entire period, but never went beyond the income of, say, a well-paid computer technician.
-- the top income tax rates going into 1980 were 50% for earned income and 70% for unearned. Reagan changed this to 50% for all forms of income for 1982-1986, then to 38.5% in 1987 and 33% in 1988.
However, any effort to combine the two rates and thereby make the claim that the increase was only (whatever)% is bogus. If your income was below the FICA threshhold, you got socked for the increase in FICA and recouped something from income taxes, but if you were in the highest brackets you paid a tiny fraction of the increase on a percentage basis (because most of your income was sheltered from FICA tax) while getting the full benefit of income tax cuts. My argument in my original post was to contrast Reagan's tax cuts vs. Bush's, but I would never argue that Reagan's tax cuts benefitted the middle class at anything resembling the rates it benefitted the wealthy. The difference is that Reagan was focused on the tax that affected his life the most -- the income tax.
Your assertion in an earlier post that the serious money is made from hard work is simply nonsense. The great fortunes in America ALL came from capital stock appreciation, with very, very few exceptions (e.g., Ronald Reagan). Bill Gates and Warren Buffett aren't billionaires because of their salaries -- surely you know this. Michael Dell worked hard, I have no doubt, but his wealth is in Dell stock, not his paycheck. Rentiers living off the wealth accumulated by their ancestors usually make virtually zero income -- dividends and capital stock sales make up their income. Reagan cut their taxes too, but Bush specifically targetted those whose income was NOT from hard work.
Money is made from hard work by the working and middle classes, and if you want to complain that their tax rates are too high, my response is that I'll sympathize with you when you make a proposal that replaces the taxes they pay with taxes to be paid by the super-wealthy. Tax money has to come from somewhere. We need armed forces; we need cops; we need schools; we need roads and bridges; we need FEMA and the FDA and the SEC. Yes, there's waste and fraud, but that doesn't mean we don't need these things. I believe it was Oliver Wendell Holmes who said that "taxes are the price I pay for civilization."
You want to cut taxes on people in one bracket, you have to raise them somewhere else. My own view is that the wealthy have a much better ability to pay than the middle class and should pay much higher rates. WHAT the rates are, of course, depends upon the needs of the country at any given time. During WWII, the rates were confiscatory but still not as high as what Hitler would have exacted from us if we did not pay those rates in order to defeat him. Today, they need not be that high but it's OBVIOUS that they're not high enough, because we have been fighting two wars with borrowed money, even when the country was NOT in a recession or anything like it.
So if what you're saying is that money made by hard working people should be taxed at lower rates so that hard work is encouraged, my answer is: fine, but then we must tax income made in OTHER ways (dividends, capital gains, inheritance) at much higher rates than at present. In fact, of course, dividends and capital gains under Bush are now MUCH lower than they are for those for money earned by hard work.
You're correct that Obama has proposed to increase the FICA threshhold, and in a manner which is designed to affect only the affluent -- I believe the target is those making over $250,000. The Moynihan-Greenspan FICA increase of the 1980s was designed to ensure that the Baby Boomer retirements would be adequately financed and, in fact, it came fairly close, though falling somewhat short due to life expectancy increases. Obama's proposal falls unequally on the taxpayers who are best able to afford it, and who are in the top 3% earning class. It is true that some of them earn that much by working hard. It is also true that many of them earn it by clipping coupons. I think Obama's proposal is by far the most reasonable way to get over what is, after all, a TEMPORARY problem.
As for the unified budget, yes, Johnson created it, and you may have noticed that the Republicans have been in power since then for 28 of the 40 succeeding years and not one has ever proposed going back to the old way, because the SocSec surplus has been a convenient way to pretend that deficits aren't as bad as they really are. What the unified budget means, in essence, is that SocSec funds are being invested in US government bonds, which seems prudent for the most massive pension plan in the world.
