This has been an ongoing issue in tech for at least two decades now. The workers in these places are generally not as skilled at software development. Their countrymen who are quite skilled have, to a large degree, moved to the US for work. My in-office coworkers from India, for example, have for the most part been at least as good as those from anywhere else including native US citizens. Those who have worked off-shore? Not so much. Quite poor, in fact. On more than one occasion I've seen units off-shored only to be brought back in a year. Companies try it because they want to save labor costs, and then regret it because the cost ends up increasing, as those who are left on-shore have to sacrifice their own productivity to make-up for the negative productivity from these workers.
