A great deal of what may be included in "homegrown talent" in the US according to this comment, indeed has come from other countries...

And the US is much richer for them (monetarily, and culturally).

But what if home countries had said, "We can give you the resources you need for your work and home life, and it will be for purposes you can believe in and feel good about; not for crypto rug pulls, nor for surveillance capitalism, nor for stunting and manipulative social media"?
