I still want to know why immigrants aren't a boon for the economy in their countries of origin.
So you are admitting what I said originally, that immigration is charity. They are coming here to have access to our better institutions and infrastructure.
No, I'm not. The things that really make America great, our justice, compassion, and rule of law aren't finite. Economics is not a zero-sum system. Indeed, economics is based upon the premise that by interacting with others, both parties are better off.
Yes, intangible concepts are not finite. Stuff that actually makes America nice to live in though, material resources, are finite though.
Again, just having a lot of people does not make an economy strong, if that was the case, India would have the best economy in the world.
There's a reason India and China will overtake the USA as the world's largest economies by 2050. Hint- it begins with p and ends with opulation
