Again, why is the answer in agriculture to simply not increase wages? Someone’s willing to pick berries for $100/h I’m sure. Does it make berries unsustainable as a business? Likely, but isn’t that an argument for moving away from industries that can only survive on exploitation of undocumented third world labor?
Ah, the argument is following it: the berries will still be picked in other countries for substantially lower wages and worse conditions than the wages or conditions (partially) of undocumented workers here. Even our worst jobs are substantially better (usually ~3x) than the average job of many countries, to say nothing about the huge gulf in security and institutions you get form living here.
That's also the argument that Bryan Caplan has been making for years in favor of open borders. I genuinely don't know what to make of it, I get the moral argument within it.
