"No they didn't, inflation increased tax revenues."
Negatory. If that were true than tax revenues under Jimmy Carter, who created levels of inflation not yet matched in the US, would have produced much, much higher tax revenues, especially considering that tax rates under Carter were so much higher. So your Maxim doesn't really hold true. Even with much higher tax rates, revenues under Carter were less than under Reagan. Do you have another explanation?
"We've have incredible increases in productivity since the 1980 without the accompanying rise in wages though the wealth has flowed copiously to the upper 1%."
And the reasons for both are relatively clear and simple. First, the changes in labor productivity were not due to a change in labor, but due to changes in capital that allowed firms to produce more with a given amount of labor. Robotics, automation, computers, etc. And those people that were providing these new services saw a big change in wages. In the mid 1970s, the wage difference between a college grad and a non-grad was about 5%. Now a college grad makes about double what a high school grad makes. Much of this is due to the change in labor demand that began under Reagan and continues to this day. A surplus of unskilled labor results in lower wages, while a scarcity of professional labor results in higher wages. Since labor has is unique amongst factors of production in it's ability to differentiate itself, the obvious answer is for the unskilled labor to become skilled.
"Yeah, as if anyone is even remotely talking about something like that."
Then what are you talking about? a 90% tax? 95% tax? Again, if the Maxim is that taxing high income earners fosters productivity, then wouldn't 100% be optimal? If not, what rate would be?
"Your rant is basicly an attempt to reaffirm the philosophy, now ridiculed and reviled, of Voo Doo economics, trickle down economics, supply side economics, Reaganomics."
Rant? Not really. This is what's taught in virtually every economics course in the country today. I have a BSBA and an MBA, and not once did I ever hear a professor suggest that high taxation was the road to increased productivity. I often heard the opposite, that taxation would serve as a disincetive to labor, or any other factor of production for that matter.
I think you may have misunderstod my position on Reagan as well. I'm not a huge fan, but I did feel compelled to point out the results of his tax policies. Reagan was a true keynesian, in that he successfully used public funds to stimulate economic growth. Most on the left have a very, very distorted view of Keynsian policy, often conflating it with a post-Marxist philosophy designed around strict government control of resources. Reagan used the issuance of dent to cover short-term reductions in tax reveunes that were a result of his tax cuts. Over time, they more than made up for themslves. Personally, I would have preferred to have seen him cut expenses along with taxes. Of course then we might still have the Soviet Union to deal with, since a lot of the expenses under Reagan involved countering the communists.
