CHRIS HAYES (HOST): Today, behind closed doors, outside of the view of cameras, Donald Trump proposed one of the most deranged policies I have ever heard. He told Republican lawmakers behind closed doors he wants to eliminate the income tax and replace it entirely with tariffs, effectively taking us back to the 19th century. This idea makes as much sense as ripping up the entire Interstate Highway System and replacing it with canals.

Economist Paul Krugman did some back of the envelope math and estimates the policy, quote, “would require an average tariff of 133%.” Not 10%. That is a 133% tax hike on all imported goods that would be passed on to consumers. A sales tax of 133%. It would cost Americans hundreds of millions of dollars. Former senior policy adviser to the National Economic Council Brendan Duke explained further, quote: “Another way to put Trump's latest incredibly unworkable idea. One—” get this, “It would raise taxes by $5,000 for a typical family,” if you’re a working person who buys stuff. “It would cut taxes for the average family in the top 0.1% by $1.5 million.”

This proposal would jack up everything, everywhere for normal people, crushing the average American's wallet, while giving the wealthiest folks who no longer have to pay an income tax and don't buy that much relative to their income, an enormous windfall. Millions and millions of dollars. This is the man who has a 50-50 shot of taking the White House, in large part because of the macroeconomic conditions that produced high inflation. And he is seriously, quite seriously and earnestly, currently running on the most insanely inflationary platform I’ve ever seen. Higher prices, higher taxes, for everyone. It would make what we’ve seen over the last few years look like nothing.
