And that is all about the economy doing better, holding to the trend that was set in motion most of a decade ago.
Has nothing to do with a tax cut that only decreases taxes on profits. You need to remember, businesses do not pay taxes on the cost of doing business, they only pay taxes on their profit.
So cutting taxes on profits will not make a business go from unprofitable to profitable, it will not increase their profit margin, it will only decrease the taxes they pay on the profits they are already making.
You are right, an economist is not going to see that. It will not increase the profits of a corporation, but rather, just decrease the taxes that they have to pay on those profits, and it will not affect the demand for labor at all.
What an economist would see that there was a steady decline in unemployment over the last several years. And when that unemployment hit the point where it really can’t go any lower, wages started going up as businesses needed to start bidding up wages to compete for workers, rather than the other way around.
