Emigrate where? And why do you assume that the country you're gonna emigrate to will have the funds necessay to fund the research? US grants are the biggest and most generous in the world. I think the USG spends over $900 Billion every year. Europe spends about 1/10th of that. Other option is China but as a foreigner, you will never get a grant there unless you work for someone else.

Hasn’t academia always been that way?

Boots. Licking boots.

There is a lot of private funding available with a broad range of targets and boundaries.

I don't think China needs the kind of scientists disproportionately affected by the bad orange man's vendetta.
