Haha, man, I had the same thinking ("Surely I can find some genius programmers in Asia or Eastern Europe willing to do the same work for a fraction of the price") but the reality is very different

I had no luck with it at all myself. I'd get completely useless low-quality crap work out of these guys when I got anything out of them at all.

I think you'd have to hire some local managers and maybe send over some experienced devs from the USA to train up the locals, at which point it'd only be a matter of time until they realize their new worth and jump ship for FAANG or whatever.
