"At least under the Ds, the middle income people do a little better so the economy does better so small businesses do better"
I guess this depends on who you're reading and who you prefer to believe, since all sides claim their numbers are correct - but everybody's numbers always seem to add up to something different.
I did find the following interesting, from a Wall Street Journal article (yes, I can hear the left leaners now - well, it's the Wall Street Journal, you can't trust it!):
"Every major marginal rate income tax cut of the last 50 years—1964, 1981, 1986 and 2003—was followed by an unexpectedly large increase in tax revenues, a surge in taxes paid by the rich, and a more progressive tax code—i.e., the share of taxes paid by the richest 1% rose.
For example, from 1980 to 2007, three tax rate cuts brought the highest marginal tax rate to 35% from 70%. Congressional Budget Office data show that when the tax rate was 70%, the richest 1% paid 18% of all federal income taxes. With the rate down to 35% in 2008, the share of taxes paid by the rich doubled to 40%."
"So on four separate occasions what TPC says is "mathematically impossible"—cutting tax rates and making the tax system more progressive—actually happened. Hats off to the scholars at TPC: Their study manages to claim that what happens in real life can't happen in theory."
"And here's the kicker: Simpson-Bowles assumed that the top rate could be cut to 28%, loopholes could be closed, revenues as a share of GDP would rise to 20% and the deficit could be cut by close to $1.5 trillion. The difference is that the Romney plan caps tax revenues at about 18% of GDP so that taxes don't have to rise on the middle class. If Mr. Romney's numbers don't add up, then neither do those in the bipartisan Simpson-Bowles plan that the media treat as the Holy Grail of deficit reduction."
"What the Obama campaign and its acolytes at the Tax Policy Center are really saying is that tax reform that reduces rates and makes all income groups better off is impossible. This is a far cry from what Democrats used to believe, going back to Jack Kennedy in 1964 and in the 1980s when prominent Democrats Bill Bradley, Dick Gephardt and Don Rostenkowski helped to write the 1986 tax reform."
