"In its finalized form, however, the Tax Cuts and Jobs Act cut the corporate tax rate, benefiting shareholders—who tend to be higher earners. It only cuts individuals' taxes for a limited period of time. It scales back the alternative minimum tax and estate tax, as well as reducing the taxes levied on pass-through income (70% of which goes to the highest-earning 1%). It does not close the carried interest loophole, which benefits professional investors. It scraps the individual mandate, likely driving up premiums and making health insurance unaffordable for millions."
