This is the same reform as 1986. Democrats may go for most of this with some modifications like they did in 1986 because it eliminates junk loopholes.
deductions are just corporate welfare anyway. The more deductions, the more forms to file. The more forms to file, the more people look to Turbo Tax, H&R Block, etc. Business capture a sizable chunk of the tax savings, and the push the boundaries of proper tax-preparation which reduces government revenues further.
Inefficiency doesn't help taxpayers, and deduction-based social-engineering is never as effective as promised.
