The tax bill was designed in a way to make people's previous withholdings inaccurate (although theoretically more accurate overall). That was politically motivated for two reasons. People were more likely to see a positive (or less likely to see a negative) impact on their paycheck from the tax bill passing. Republicans have also historically wanted to make the act of paying taxes more painful for the average American on the belief that it would generate political motivation for lowering taxes. Tweaking the withholding rules to result in larger payments (or lower refunds) when filing taxes is part of that plan. Both those points have nothing to do with whether the overall tax plan was beneficial for the average American or the country at large.
