It's as if you don't spend your cash if your cash-pile is only 7 miles high, but do when it hits 8. All these cash-rich companies announcing bonuses are just spreading trickle-down propaganda.
The Kansas tax-cut experiment has shown that general tax cuts hurt the budget far more than they help the economy, if any. (GOP likes to point out that Kansas's jobless rate decreased after, but it did so at the same rate as the rest of the nation. Spin.) The real test for this new "experiment" will be when a recession hits and we need a rainy-day infusion. What happened to all the fiscal conservatives who were so vocal before Trump?
Our corporate tax rates were about the same as Germany's and Japan's if you factor in loopholes actually used. Those are the two top-performing democracies in the world, besides US. If their rates are somehow sub-optimal, it didn't hurt them enough to knock them from the top two positions. I'll take actual results over pundits as the best evidence for the results of tax cuts.
Now, I'm not necessarily against lowering our corporate tax rates some, but we have to be mindful of the budget deficit and not over-do it. And, GOP didn't have to lower personal tax rates for the rich. Their priorities are out of whack.
