FROMA HARROP: The SALT tax deduction is actually progressive

No serious economist believed that former President Donald Trump's 2017 tax law would pay for itself. On the contrary, that buffet of tax cuts will explode deficits by almost $2 trillion over 11 years, according to Congressional Budget Office estimates.

Though the benefits went overwhelmingly to the highest-income Americans, red-state Republicans cleverly added an item that purported to raise some taxes on rich people. But not so much their rich people. It primarily targets those in high-tax, high-income blue states. We speak of the $10,000 cap on the state and local tax deduction, or SALT, designed to drain revenues from the likes of California, New York, New Jersey and Massachusetts.
