There was no data there prior to 1980. Eisenhower was president in the early 1950s.
Did you not see the "vs." in my post? I compared the two.
You have not made the case. The Tax Foundation website policy statements write more like me and believe what I believe far more than they reflect your beliefs.
This isn't about belief. That is the whole point. Even someone at the Tax Foundation will tell you that Eisenhower's rates were higher. That is fact if you are basing it on this AGI data- not belief. I have nothing for or against the Tax Foundation, I don't know why you are even bringing up their advocacy positions. You seem to have an issue distinguishing between fact-based matters and opinions. Now if you have an issue with the methodology of any of these studies or the logic behind my conclusion, then pleas enlighten me on where I am wrong. And by that I don't mean attack me with myths from your head (like I am a communist), but show me where my methodology was wrong.
Until one has a good understanding of the impact of tax shelters on adjusted gross income it will be difficult to establish what the effective tax rates were. When one has data labeled effective tax rates on amended adjusted gross income one can only wonder what value they provide. Those words could mean just about anything and I suspect they do. It reminds me a bit of Alice in Wonderland.
What about their methodology do you not like? Is there any data out there in the world that helps make your case? Or are you the only angel is a world of commies? Show me the data for your argument.
And please note that through all this I have not made any claims about what tax structure I prefer other than that I prefer a progressive structure (as have most of the Republican presidents in recent decades). All I am saying here is that the Eisenhower vs. Obama/Bush effective rates are a matter of fact and the data strongly if not conclusively suggests Eisenhower's rates were higher.
