It comes down to the same thing as democrats saying "tax cuts" need to be paid for.
If they hadn't spent so damn much in the first place, they wouldn't have needed to raise the taxes so high, so we could eventually cut them (albeit marginally).
If those corporations managed to evade paying some taxes by using some loopholes for so many years, then it's the governments job to make their budgets fit with what taxes they do collect, not keep increasing taxes to pay for their increased spending.
If some projects come up that aren't allotted for in the budget, then a temporary increase could be mandated, and then once the project is done, the tax is eliminated. The problem is once a tax is increased, or added, it's mighty difficult to keep the democrats from eliminating it once it's not needed any longer, they just find new ways to waste spend it via earmarks, and pet projects, or just make-work projects to keep the money flowing to them so the next years budget can show that it's "needed" for future uses.
