Probably won't mean a hill of beans to low or moderate income folks like me unless you spend more than you have in order to accrue tax payments in excess of standard deduction...just like any other "deduction," it is all a shell game. IMO.
The answer is a National Sales tax, IMO of course.
Let the flamers get started.
There will be tables but you are correct. They don't have enough income to make much of a difference and this deduction is on taxable income. It's not a tax credit.
But the idea that the "poor" won't be helped is not a good arguement since they, being poor, don't have enough income to benefit from any tax cut unless it's in FICA. But the problem there is the majority of the poor (the truly poor, not the statistical poor based on government definitions) probably need to pay into FICA since they'll be more than likely the ones needing Soc Sec and Medicare. For the rest of us those are just income redistribution programs.
