Companies got a tax cut and did a trillion (with a t) dollars worth of stock buybacks. That's going to boost the stock price up for a bit...but the repurchases are done...now it's back to business as usual. Remember last year when companies were handing out $1,000 bonuses like it was halloween candy? And that was BEFORE the tax cut. Nothing this year.
Trump supporters won't admit it, but the tax cut failed. You were promised that the money saved by corporations would create new jobs or increase the pay of existing jobs. From about 2010, most companies gave the obligatory 3% raise. Then we got a tax cut and companies, flush with new cash gave....a 3% raise.
