The Bush tax cuts were "temporary" because we lacked enough Democrat votes to make them "permanent!" If the cuts expire, taxes increase, THUS, there would be an effective tax increase! DUH!
And as for fact, I have presented them, you don't understand or don't want to try and understand, but that's not really MY problem.
Why do you think KENNEDY wanted to lower top marginal rates? Like I said, go do your own research, I don't need to post links to sources which you and others can pick apart with your typical bullshit, the information is out there all over the Internet, and you are invited to dig into it, if you don't take my word for it. You'll find, every time we've increased the top marginal rate, the revenue-to-GDP has declined in subsequent years. There is a slight increase the first year, but after that little bit of a gain, it's all loss! We LOSE revenue by increasing the top marginal rates! Additionally, every time we've reduced the top marginal rates, it has resulted in an increase in revenues for the years to follow. This has been well documented by the Heritage Foundation and others. What is even more important than this fact, is the reason WHY that is the case, which apparently, you don't get! When you reduce the tax burden on the top marginal earners, you free up capital which is often used to invest in new business, upgrading existing businesses, hiring new workers, expanding, and growing the economy in immeasurable ways across the board. The end result is, people make more money, and in turn, pay more tax dollars, even though their actual rate of taxation is lower.
Every true conservative who understood Reagan's economic principles and the principles of supply-side economics, believe as I do. Keynesian idiots, and clueless dolts like yourself, want to argue CLASS WARFARE and make "the rich" some evil entity that we need to punish for their success. That's because they wish to implement a Socialist Marxist system, and to do that, they need to bring down the capitalist system. They do appreciate you help in accomplishing that objective, and please don't be offended by the term "useful idiot" they have applied to your type, it's just a name.
