During the campaign, President Donald Trump floated an "all tariff policy" he said would replace federal income tax. Here's what economic policy experts say.

Higher tariffs could worsen the squeeze on American families by increasing their taxes, lowering their income, and requiring them to pay more for tariffed goods.

The Trump administration hasn’t given up on the idea, according to Peter Navarro, a top adviser to the president who said Tuesday that new revenue from tariffs will be used to eliminate taxes on tips. That comes even as Republicans struggle to come up with enough revenue to make Trump’s 2017 tax cuts permanent, at a cost of more than $4 trillion.

We have an income tax as opposed to a tariff in part to deal with the mind of the South in 1913—yet the income tax revenue enabled revenue-destructive tariffs.
