@KirkegaardEmil Land border w Mex- ppl who want to come here already do, illegally; uncapping immigration would unblock huge backlogs for India & China work visas.
@KirkegaardEmil And it's funny, my Mexican econ boyfriend was the one who asked his prof Caplan to sign my copy of Open Borders... His parents left school with elementary education, came here illegally to work as gardener and nanny, their kids are 3/3 degrees and high paying jobs.
