Right away I see two deductions that could be greatly modified or eliminated.
First would be the mortgage deduction. Ideally, it should be eliminated. Those people who rent should not be subsidizing homeowners. At the very least, the deduction should be limited to a certain amount and then only on a primary residence.
Just about every one of those deductions is for a right or to increase jobs and GNP in the US or to avoid double taxation.
As soon as they are eliminated, more jobs will disappear and less rights defended.
The present move is to pay Fed income tax, then state income tax on the same income, then paying sales and property taxes additionally. In many cases this becomes double and triple taxation.
We won’t be paying a 10% tax but everybody will be looking at about a 40% tax. This also implies all merchants and landlords will have to increase their prices to keep up with the additional taxes.
All this does is shuffle the cards as to who gets paid, with the govt getting paid first without incentive to decrease spending.
It would be smarter to make a 10% flat tax distributed between all government. (2% sales local municipal level, 2% county/parish level, 3% state level and 3% state level).
