There is a lot more to it, I agree, but an across the board slash of rates, particularly in the corporate sector weren't the answer.
Currently the IRS has a program where corporation's get large tax credits for hiring folks who have received public assistance, have criminal histories or were displaced. This credit could have been massively expanded to be larger and to extend to offering credits for worker training, continued education and relocation assistance. The benefit to the employer being a complete offset of the worker's salary, with a broader economic benefit of employing someone who'd likely continue to be on aid.
The IRS could have additionally extended the amnesty of repatriation of assets so long as the funds were invested in hiring, infrastructure development, or to a lesser degree asset acquisition and stock buybacks.
