Your scenario leaves a lot to be desired.

Yeah two people only.

Well Your scenario can easily be countered with the imaginary scenario that you have a town with 1 billion residents, far too little housing, no green space left due to trying to provide housing and the city only has natural resources for perhaps 300.000.000.

Now 100.000.000 immigrants arrive. There is not enough food, water, hygiene. Hopefully, opening delis will solve the issue.

Yes, it is absurd. But no more so than a world of 2.

History though does prove your theory right. When proud and brave Europeans immigrated to what would become the United States.

"When they arrive there are no stores to buy goodies from because who would create such a store for just 2 people? Perhaps an immigrant, could open a deli!""

Thankfully for the native people's immigrants came in to create a consumer capitalist culture.

Can you imagine the utter horror if they native peoples were allowed to keep their versions of society going and develop it the way they wanted. They sure were blessed by the immigrants. A lot the natives' peoples also became xenophobes and we sure now what bastards' xenophobes are.

This is silly because you don't have to imagine any scenarios. Good economic models are based on empirical data, not on imagining things, and "immigrants don't increase unemployment or decrease wages" is just about the strongest empirical result there is.

The reason being that someone moving closer to you increases demand for labor more than supply, and immigrants generally have complimentary (slightly different) skills to natives. So the person whose labor the immigrant most competes with is another immigrant.

As for remittances/brain drain, there are certainly theoretical issues but it seems to be okay in the end because it boosts investment in the originating country.

And if you subscribe to MMT you should love immigrants because they're free "unemployed" people you didn't have to spend money raising so you have greater runway to print more money without inflation.

And if they are illegal immigrants, even better, they will work hard for a very small salary. They even do very little crime because they don't want to be thrown out of the country.

I think in general immigration from say Mexico to US is a loss for Mexico and a win for US.

Country of two people is not hard to imagine, think of a desert island with Robinson and Crusoe.

Overpopulation could be a problem but when people become better off financially they for some reason tend to have fewer children.
