Then why have any immigration laws at all? If every possible immigrant is a positive contribution.

But… if some are a drain on your limited resources, unhealthy competition for your most vulnerable, or just plain dangerous to your values, then you need immigration laws.

Which is what pretty much every country on earth has concluded. Even the poorest.

Literally nobody is arguing that there ought to be no immigration laws at all. But obviously we can treat the families of natural born citizens better without completely letting the whole system fall to anarchy.

Why mentioned illegal immigration? That should be illegal in the first place. What Trump does is temporarily suspend ALL immigration.

There's a drain on limited resources but the idea in America was to attract all the talent and this resulted brain drain in other places, which for a US was a winning point. So, maybe this is a good thing, for other countries??

And let me remind you the real reason the limited resources are being drained the most: the rich eschew their taxes through tax heavens and what not. It is easy to blame it on immigrants to move the attention away from the tax loopholes and other shenanigans the super rich are doing.
