I have wondered what that would be like. I have grandchildren, and have no desire to see them go through this looming train wreck. Having children (and childrens' children) is great, but it is also a graduate course in dealing with worries over which you have zero control.
Either way you go, there's no turning back.
FWIW, I have had no regrets about that decision made as a teenager. I never wavered. It was not easy finding a woman who would go along with my choice but I found her, to my everlasting delight.
I can just imagine the emotional torture that people in your situation must feel. Who could have known that the USA would deteriorate so badly?
