First, let me declare my enduring ignorance when it comes to economics, so if what I'm about to say is wrong or makes no sense, just give me a sarcastic smiley and move on....![]()
I don't use smilies, and I'm not going to ridicule you. Economics is hard, and I'm no expert on it either.
Looking at your link (thanks for the info), it seems that while total receipts remained constant, tax receipts for individual and corporate income actually rose and fell with the tax rates.
If you're looking at the link, which has raw numbers as opposed to being a graph, then you're looking at receipts by source of tax revenue as a percentage of GDP. Thus, those aren't numbers representing gross receipts from taxes. They are expressed as percentages of GDP.
If you are looking at the graph (not the Laffer Curve), then again, you are looking at a blue line showing federal income taxes as a percentage of GDP and a black line showing total federal tax revenue receipts (including social security and excise taxes) also as a percentage of GDP. The heavy black line at the top of that same graph denotes the highest marginal tax rate for the highest income earners. It varies tremendously over time. The other two lines don't. The point is that varying income tax rates for the top earners does not affect tax revenue as compared with gross domestic product, which is the most commonly used indicator of the productivity of the nation. Roughly, it means income tax revenues rise and fall with the nation's productivity, not with the tax-the-rich schemes pushed by class warfare advocates.
This is what fuels the supply-side economist who claims that if you want to raise federal income tax revenues, you should provide the entrepreneur and high income earners every incentive to increase productivity and to make more money. That will generate more gross revenue for the federal government because GDP will rise (the federal revenue generated will remain approximately 19.5% of GDP, but the absolute numbers will increase). Hence Reagan's mantra that a rising tide lifts all boats. Of course, macroeconomics is far more complex than simply being a factor of tax policy, so it doesn't really work that way in practice. There are "natural" business cycles that occur, local and/or temporary scarcities and gluts of goods and services, varying unemployment rates, interdependence on foreign goods and services, international monetary and currency fluctuations, natural disasters that affect markets, and so forth.
From 1948 to 1964, when rates were at their highest (in your graph), total individual and corporate income tax receipts averaged at 11.81%. From 1965 to 1982, when the tax rate dropped, receipts averaged in at 11.11%. From 1983 to 1986, when rates were drastically lowered, receipts went to 9.4%; the same with 1987 to 1994, they were at 9.77%, and then from 1994 to 2000, when rates were raised slightly, receipts were at 11.3%. Moreover, corporate income tax receipts as a percentage were consistently under 2% during the lowest tax rates and consistently above 3% (and sometimes much higher) during the highest tax rates.
So, while total receipts remained constant, it was due to other factors such as the increase in Social Security and Retirement receipts over the years. With the cap on Social Security taxable income at $90,000 (I may not be saying that correctly, but hopefully you know what I mean), is it fair to say that Social Security is a tax that hits lower and middle classes harder than income tax rates, and by reducing the rates and amount corporations have paid in income tax and increasing the Social Security tax, we have effectively shifted tax burden from corporations to the lower and middle classes?
That's very close, and shows good insight into the issue. Actually, the social security tax hits the middle income earners with the greatest impact, as a share of the total burden. That's because it's not progressive, so its impact tapers off on the higher income earners, and also because the marginal rates are lower for certain types of income, so the burden is reduced for lower income earners.
Look at the graph in this link which illustrates this point. Again, sorry I can't post the whole thing, so I'll just have to link to it.

The source is newsbatch, which is apparently run by a lawyer in California. His graphs are generated from government sources, so I don't doubt their accuracy. If you are interested, I recommend wading through his brief slide show on taxes, which includes charts on sources of federal and state tax revenue, and also on federal budget expenditures.
