I don't know about stimulating job growth, but I do believe the unemployment rates will go up if the tax cuts are ended.
The people who will be hurt by ending these tax cuts aren't going to hire more people if the cuts continue, but if you take them away the results will be, I believe, devastating.
If you tax a business, they up their rates. If you tax fuel, the trucking companies charge more to bring in goods, which we pay more for at the store.
I believe that thinking "we'll tax the rich and that'll bring us more money" is naive. Profits will stay the same, everyone but the businesses and the extremely wealthy will lose.
