When rich people get a tax cut, they buy stock and real estate.
When corporations get a tax cut, they repurchase their stock shares to inflate the price, increase CEO pay, and increase their dividends.
These people don’t suddenly hire more workers because they got a tax cut. They already have plenty of money, more money won’t suddenly make them hire you or increase your pay.
The only thing that increases the number of jobs is an increase in demand. And increase of demand is achieved when workers and average people have more money to purchase goods. Higher wages for workers = more demand for goods = more jobs This isn’t calculus, it’s economics 99
