One of the things we do at the Indicator is steal stuff we like from other podcasts. Today, we're stealing from Tyler Cowen. He's an economist and public intellectual who has his own podcast (of course).

It's an interview show, and in the middle of every episode Tyler does this thing we love: He goes through a list of subjects and asks the guest to say whether each subject is overrated or underrated, and to explain why.

When Republicans launched their tax push this fall, they said, here's the plan: We are going to lower taxes for people and companies. And part of the way we're going to pay for that is by getting rid of loopholes and special deductions and lots of little perks hiding in the tax code.

Today on the show: What happened to that plan, and what it says about the way our tax code works.
