What taxes should he increase to make the reduction in corporate taxes revenue neutral? FWIW, I'm actually in favor of eliminating corporate taxes altogether, but combined with increases in taxes on the wealthy (myself included) to compensate in total revenue.
The issue if pollution regulation is complex. The are in the US is better than it was many years ago by an amount that matters - Los Angeles use to be really bad (I remember personally). There is some crazy environmental regulation but its difficult to separate from the really necessary stuff. I'm certainly glad to see the end of leaded gas, reductions in diesel emissions, car emission etc. These have had noticeable effects on my personal quality of life. (I grew up in a heavily industrial area - and pollution was a real problem). So I'm fine with the idea of smarter regulation but need details. If the big limits stay in place (which I would like them to) I doubt it is a major impact on industry.
There is a big issue when environmental regulations force work to other countries with even worse regulations. This is a tricky trade subject that should be addressed.
CO2 is of course a different question. I'm convinced of anthropogenic climate change. I'm a professional scientist, and all of my associates agree. (we are not in a field related to climate science, no personal stake in this). It seems to be selfish and frankly wrong for the US to stop working on this when the great majority of the rest of the world is (yes including China - the are behind but working hard at it).
I don't see massive gains in employment from this. The rate now is about 5%, which is close to a natural unemployment rate in a typical economy. (natural meaning that few industries want to hire the lowest 5th percentile employees for anything, so unemployment rarely gets very low).
Wages are low, but that is different from unemployment.
Lower the corporate tax rate. If you think that is detrimental to American workers you are wrong.
Eliminate the onerous environment regulation that Obama did to please his base. If you think that will lead to more pollution you are wrong.
Both will have massive impact on job creation. I can go on forever.
Before you laugh, I am one of the corporate "they" that finds global locations to build manufacturing plants.
