Republicans try to cut taxes and regulations all the time. How else do you propose to sustainably help poor people?
"cut taxes" uhh...yeah, that extra $36 a year will really bring them out of poverty huh? I believe that was the average saving for middle class people from the 2017 cuts (and conveniently those are temporary).
I don't see how cutting regulations is supposed to help poor people, the only regulations they cut help big business. If the regulation helps keep poor people down like regs limiting unionization or marijuana prohibition the Republicans always seem happy to keep the system in place.
Cutting taxes for businesses will also allow them to hire more, as recent American history has repeatedly shown.
This has never, ever, happened.
Corporations do not generally hire people because they got a tax cut, and anyone who thinks this is a pants-on-their-head moron. All it means is they keep more of their profits. It often goes to executive bonuses if it goes anywhere. Having more money doesn't mean they suddenly will be willing to hire people that they don't need - a company always has enough people to operate.
If anything, raising taxes leads to more hiring or at least better wages - because the company would rather spend the money on salaries as a business expense than pay it to the government.
