Well, for us, things have changed significantly since the cuts. We bought house, had a baby, sold the house, bought another one, and had another baby, and I stopped working, cutting our income in half. However, all things considered, we definately saw a difference in our taxes, but it's difficult to quantify since things have changed so much for us personally.
I think what some peple fail to realize is that these tax cuts only mean something significant to the middle class. The uber rich..well, what difference does it really make? (Not that it's fair to take ridiculous percentages of their money in any case) and the lower income people hardly pay any income tax as it is, so how could they really see a huge difference in their tax bills?
It's us schlops in the middle that get reamed hard by the ridiculously complex "progressive" tax code.
I say, flat tax and/or a consumption tax. No deductions, just a flat rate, the same rate for everyone. Period.
Then, no one could complain about the loop holes that those evil rich people use to get out of paying taxes. With the addition of a consumption tax, the government would still be able to "get more" out of those super mean, rich people (like Whooopi Goldberg and Barbara Streisand) because they buy more with all their ill gotten dollars. <grin>
