The article doesn't say the tax cut didn't help most people. It makes the point that most people didn't notice it because they only pay attention to their tax refund. Their tax refund is going to be lower because they paid less taxes over the course of the year. They are less likely to notice those incremental payments, but it's disingenuous to say they didn't receive a tax cut. Ideally you want your tax refund to be $0 and invest the money instead of overpaying taxes. Basically it boils down to who can manage your money better, do you need Uncle Sam to hold on to your money or not.
