The so called "Trump tax cuts" were broad based. The only income group that didn't get a tax cut was those making $10k or less, that federal income tax rate stayed the same. Most tax bracket rates went down by 2-4% AND the brackets were re-done to lower thresholds, meaning in some cases, tax rates went up. As an example, Americans making $38,700 - $93,700 previously had a tax rate of 25%, that went down to 22% AND the upper end of the bracket was lowered to $82,500. Another example, previously the US had a $195k to $425k tax bracket where the income tax rate was 33%. That bracket's rate was reduced to 32% AND the bracket was re-done to be $157k to $200k. And everyone making over $200k to the old threshold of $425k, the rate went up to 35%, when previously those making $200k to $425k would be taxed at 33% (that would be a tax increase).
So no, the "Trump tax cuts" weren't simply about tax cuts for the rich. They were broad based cuts, generally. AND, some rates went up because of the changing of bracket thresholds. But of course, you didn't know that because why let facts get in the way of your narrative! LOL
