Depends on how much you want to pay for goods and services, and how competitive you want US business to be (or not be) relative to other countries.  

Income taxes in this country ARE very convoluted.  So is the issue of trying to balance spending and revenues (witnessed by the fact we've failed at it in nearly every year for the last half century).

The goal should really be to make it all LESS convoluted.  Reducing (even better: eliminating) deductions/breaks/credits and lowering the base rates is a move in the right direction. But of course, unraveling the convoluted is convoluted in itself, since people that now get those convoluted breaks will lose them (albeit somewhat offset by the new lower rates).
