Yes...they did get a tax cut. But from the fiscal times article
But others say the small size of the tax cut for many workers – the middle fifth of earners received about $20 a week on average –
So yes...everybody got a tax cut. The tippy top of the upper income got a new Mercedes or Bentley or Lexus, but the rest of us got $20 a week. And because of Republican inaction, their health insurance costs continued to rise, so that may have been eaten up by that that the net to them may have been zero.
I have also said that a LOT of Trump voters would view "tax cut" as "bigger refund". But withholding was changed. So when the end of the year rolled around, the refund was significantly less. I recall that my check went up a lot more than I thought. I went to the IRS site in March and ran the calculation. Good thing...it showed that I would have OWED about $1,000 at year end. So yeah...most of us got a tax cut. But few of us could remodel a kitchen, buy a new car, or take a vacation on what we got.
