All of the above. More Americans puts us in a better position to compete against China and India, and we can't expect our technological superiority to give us an edge forever. My view is of course biased, but I sincerely believe the world would be a crueler place were Chinese culture and military power to replace American cultural popularity and military power.

So I guess you want immigrants but not Chinese immigrants then? Otherwise they would bring their cruel culture to America?

I'm an American and I want there to be enough nurses and orderlies in American nursing homes when the time comes that I need them.

I’d rather go quietly into the night when the time comes that I’m not self sufficient (via assisted suicide). Perhaps that’s wishful thinking, and I won’t have the mental fortitude at that time.

Also likely, "culture of life" virtue signallers will prevent you from doing what's right for you by nudges that make suicide difficult, painful, and illegal. Part of your plan should be to support assisted suicide politically. For example, Neil Gorsuch wrote a book advocating against euthanasia, making him one of the worst Supreme Court picks I can imagine. https://press.princeton.edu/titles/8317.html
