How about "tax the living hell out of capital" on a spending-neutral basis? Pay off the debt. Stimulate local economies. Increase the EITC ceiling. Hell, write a simple UBI statute.
There are lots of easy (and easily verifiable) ways to spend government money on things people value. That you think there aren't is sort of the triumph of modern conservatism in a nutshell.
Otherwise, "tax the living hell out of capital" will just cause some more big BOOM sounds somewhere in middle east, and deplete private capital from making more investments at the same time.
