Really? Can you give me some links to where this has been "proven"? I enjoy pointing out the holes in arguments "proving" things that are false.
Actual tax revenue data contradicts your claim. While it is true revenues often increase after tax cuts -- they increase almost every year, after cuts, after increases, after taxes are left unchanged -- there are also examples of tax cuts being followed by decreased revenue. The most dramatic example (of the last 50 years, at least) was under GWB, who had an unprecedented four-years of reduced revenue following his tax loans. This has been well documented several times here.
Here are links to two of the more recent threads:
One of my comments from one of the threads:
"No it hasn't, as you well know. Record tax revenues for 41 out of 45 years ... and then Bush came in with his costly tax loans and had an unprecedented four year failure to increase revenues. Clinton had record revenues eight of eight years, in spite of his supposedly "huge" tax increases. Bush 41 was either 3 of 4 or 4 for 4 (don't rememebr off the top of my head). Reagan managed seven of eight. Carter, Ford, Nixon, Johnson, Kennedy, etc., all had record revenues most years, through tax increases and tax cuts alike. Only Bush 43 showed such dismal performance.
"That doesn't prove cause and effect, of course, but it nicely refutes the myth that tax cuts increase revenues. They didn't for Bush 43, and that's a fact."
Here's the actual data from the CBO. See page 26 for the relevant data:
Very much agree. Unfortunately, the tax cut zealots generally point to increased tax revenues as "proof" tax cuts increase revenue ... while ignoring the contrary examples and the fact that tax revenues almost always increase, including after tax increases.
I can't speak to what these "groups" purportedly try to show. It has nothing to do with anything offered in this thread, however.
I generally agree with this. Ideally, in a recession we want to put as much money as possible into the economy which means lower taxes and deficit spending by Uncle Sam is reasonable. Unfortunately, our debt has grown so high that increased deficit spending may be even worse. We have to reduce the deficit somehow, and increased taxes on those who can best afford it seems like a reasonable concession.
I can't speak for everyone, but those seem like gross distortions of the positions of most people I know, to the point I think they can be characterized as straw man arguments.
