I suppose it depends on whether or not you consider it morally acceptable for a country to prioritize the prosperity of its own citizens over that of non-citizens.
I.e., whom does a country's government serve?

Edit : Sorry addicted, I interpreted your comment as a justification, not as historical account. My bad.
I think GP was giving a causal explanation in terms of political history.
Two parties disagree and eventually one says to the other "if you don't stop it I'll make you stop it."
This is a truth claim that can be honestly verified through physical struggle. If they win, then their might did make them factually correct. If the other side was mightier than the other side proved themselves correct when they said "no you won't."
No?
Edit: human beings since forever have never stopped warring with each other over stuff. It's almost like our M.O. is Argumentum ad hominem, ad baculum, ad infinitum - "argument by beating a man with a stick for eternity"
Are you arguing that two human attributes in particular, race and birthplace, should for some reason be subject to the same level of discrimination in hiring?
Or are you asking a more abstract question? I.e., given any human attribute ${attrib}, what are the principles a government should use when deciding if ${attrib} is a legally protected class?
Also, I think there is a big difference between allowing discrimination (which is only wrong if you belong to a protected class) and requiring discrimination, which is pretty much always wrong.
So its one thing to argue about whether employers should be allowed to discriminate against foreigners (or blacks). There are some good arguments on both sides. But I don't think there are any good arguments in favor of requiring that employers discriminate against foreigners (or blacks).
Not on your own. You need to find a country willing to accept you as a citizen. For the vast majority of people in the world, the only countries that would accept them are those where they would be worse off. So the countries that do (successfully) prioritize prosperity of their citizens also effectively lock out most people from elsewhere. The trickle of immigration is just that, a trickle - it is deliberately constrained with various rules and requirements, and it would be a much bigger stream if anyone who wanted to change their citizenship could apply (even if you filtered out, say, people with criminal records and such).
You know that's not true, and other countries have much more strict citizenship processes, some not even allowing full citizenship.
Imagine I'm a cab driver in Pakistan and want to become a cab driver in the US. Can you point me to what form I would fill out in order to apply for a visa?
As far as I'm aware, no such process exists.
