The Fed Gov should stop spending on crazy "studies", over payments for for normal goods, crony deals, the damned ILLEGAL INVADERS, payments for so-called farmers, who really aren't framers at all, ever bigger government jobs/duplicate government jobs, and on and on and on.
This so-called "tax cut" mess DOES indeed "pick winners and losers", which it should NOT do!
It merely changes winners and losers. People paying high rents are currently losers. They will get a more level playing field with mortgage payers.
People living in high tax states who benefit from deductions by definition have the means to move to a low tax state.
