Paul Ryan and Donald Trump, ostensibly the two leading politicians of the Republican party at this point, hardly overlap in their long-term visions for the U.S. economy.

One of their emerging differences is how each views the federal government’s debt. Ryan sees the country’s total obligations as an urgent matter, increasingly ominous and fixable only with the restructuring of Medicare and Social Security. Trump has expressed similar alarm about the immensity of what the nation owes its creditors—but he personally “loves” debt, loves “playing” with it, would be open to taking out more of it to fund infrastructure spending as president, and instead of paying it off in the long run with changes to federal entitlement programs, he’s said he’d knock it out in eight years by renegotiating trade deals.
