Already several (R) Senators are against the new tax scheme so it doesn't look likely to pass, and especially not before Twittler's Xmas deadline.
The removal of the state and local tax exemption and student loan interest exemption is going to particularly hurt younger taxpayers. My two youngest daughters are good examples. They both live in high-tax states (IL and VT), both carry student loan debt, and both have mortgages. As it is now, they get a small refund (IL) or owe a small amount (VT). They both itemize. Remove those two exemptions and both will end up paying quite a large amount. They are ages 30 and 32 -- the prime demographic that retailers and advertisers covet because they tend to spend more of their discretionary income than we oldsters do. People like my husband and I won't pay more since we don't itemize; but we also don't spend much because at our age we have already procured household goods, car(s), clothes, etc.
If you want to wreck the economy in the most efficient manner, raise taxes on those who actually are job creators -- the people who buy products and services.
