And that seems unrealistic.

IMO we would be better off closing other loopholes:

- various special carve outs (real estate stuff, carried interest, etc)

- enforce the estate tax for real

- ban stock buy backs, make companies return cash via dividends, which are easy to tax

- remove special treatment for capital gains

- hire lots more auditors and lawyers for the IRS to go after high wealth returns, where all the fraud is
