Tuesday’s proposal comes two months after the president released a so-called “skinny budget” previewing changes to discretionary spending, the 30 percent of government that is appropriated each year, unlike “mandatory spending,” like Social Security or Medicare. In that budget, Trump sought a big increase in military and border spending offset by cuts to science funding, the State Department, and environmental protection. The skinny budget was notable for shutting down some of the few economic programs that specifically help the Rust Belt and Appalachia, starving research universities of the funds that often power local innovation.

In short: Trump’s budget would almost certainly increase the number of uninsured Americans while hurting poor families, especially those that rely on government support in Appalachia and the Rust Belt. But that’s not all.

It’s critical to assess Tuesday’s budget along with the White House’s tax plan. Its centerpiece is a proposal to lower the tax rate on “pass-through” income to 15 percent. This change might seem like a middle-class tax cut, since most businesses are small pass-throughs, like small barbershops or sole proprietorships. But 80 percent of all pass-through revenue is actually taken in by the richest 1 percent of small business, which means a large rate cut for pass-through income turns out to be a windfall for the rich. According to the Tax Policy Center, the proposal “would add $2 trillion to the debt over the next 10 years, while distributing nearly all the benefits to the highest-income households.”

In the biggest picture, the Trump budget is a multi-trillion-dollar transfer of post-tax income from the poor and sick to the richest 1 percent. This not only explicitly reverses many of the president’s campaign promises. Even stranger, it represents an extraordinarily unpopular vision for government by a president who is obsessed with demonstrating his own popularity.

Trump is devoted to destroying the Affordable Care Act at a time when support for it is at an all-time high. Meanwhile, the replacement bill, which Trump has repeatedly praised, has an approval rating of just 21 percent. The White House’s proposal for a historic tax cut, one of the largest in American history, comes at a time when 77 percent of Americans are opposed to cutting taxes on the wealthy. Meanwhile, his budget dismantles parts of the welfare state. But in a recent NBC/WSJ poll, 57 percent of respondents said they want the federal government to do more to solve people’s problems—the highest level in the history of the poll, going back to 1995.

So, what, exactly is Trump thinking? A simple answer is: He isn’t. The president has never demonstrated a deep affection for the inner-workings of budgetary procedure or policy. He often seems at a loss to explain even the basic details of his own policies. As a result, perhaps he’s turned over budget-policy writing to traditionally conservative Republicans with a handful of guidelines—e.g., don’t cut Medicare, don’t cut defense spending—and decided that it’s easiest to simply support whatever they come up with, even if it’s a violation of his campaign promises.
