Some of the arguments do, but others hinge on culture and human capital retention and transmission across generation in existing communities.

Other arguments hinge on government payouts to crossers (more fiat printing), the non-taxable income many crossers generate, and remittances back across the border.

Wealth-generating for who?

1) Employers

2) Those crossing the border

3) Who else?

This sounds like it might rest on a Libertarian+David Ricardo foundation, but the problem with Ricardianism is that comparative advantage isn’t an advantage anymore when foreign nations control your Pharma, weapons, manufacturing, etc. supply lines.

And when cheaper labor drains the expertise/human capital of a community 20 years hence (e.g. now), getting back the skills to build again takes 2 generations.
