For the first time in a while, there’s political momentum building to change the U.S. immigration system. On today’s show, we ask three economists: What would the perfect system look like? If we could scrap the mess of a system that we currently have and replace it with anything, what would it look like?

  • Let in lots more doctors and engineers
  • Auction off immigration slots to the highest bidders
  • Open the gates, and let everyone in
