Belief in infinite growth stems from an inability to understand how the exponential function works.

There is no such thing as indefinite growth, there is logistic growth between steady states. Pretending that immigration is always good is like pretending that drinking water is always good. Useful when you're in the Sahara, less so when you're drowning.

The US is currently in a situation where the labor market has an oversupply of people which is why real per hour worked wages are still at the level they were in '72. Adding more immigration now will only lower the living standards of the people already here, this will be the case until we increase the carrying capacity of the US economy with better labor laws, more government spending on fundamentals and better targeted research.

Indefinite parabolic growth (at least, for billions of years) is possible.

If you're going to be the one that explains to shareholders why their dividend is dropping each year but will only asymptotically approach zero so they should not fire you, by all means try. Somehow I don't think you'd be successful.
