what he had to say because he's a one sentence, gotcha guy, and that's it. Full of it. Economy has been running at a fair clip for quite some time now, and it's been some time since the last downturn, 9 yrs or so, after Obama won and got into office.
All this tax cut of 2018 is going to do, is deepen the federal debt (proving that the republicans really weren't interested in paying down the debt, being that they passed this 2018 tax cut law w/o corresponding reductions in federal spending elsewhere to pay for it, like they did on many of Obama's bills to Congress (I recall this, they stalled and everything else they could do (repugs) to not let his legislative attempts go through)).
Steam is running out. Businesses I think have already tapped the markets so much w/ debt, stock buybacks, and the like, and the money from the 2018 tax cut law didn't flow into the hands or pockets of consumers, it went into stock buybacks etc., which simply overinflated the stock market pricing which is going to cause problems down the road. Consumers simply didn't get any money out of the deal (inflation is eating it up, any minor gains), and w/ rump tariffs and market disruptions caused by rump, tendencies are to restrain spending on the part of consumers.
