Tucker Carlson welcomed May Day protest organizer Steven Choi to his show Monday night to discuss the logic — or lack therof— behind many marchers’ reasons for protest.

Carlson tells Choi that while he’s not anti-immigrant, the influx of immigrants is “one of the reasons that wages for American working class families have stayed stagnant or declined…. you’re advocating, in effect, for lower wages for workers.”

Watch the two battle back-and-forth over simple economics.
