That was an issue where I was visiting because basically 90% the non-retired adults were working on the coast, 2 days away, and let children with their grandparents all year round except for their vacations. Apparently that created a kind of 'lord of the fly' situation in some villages, but don't quote me on that, I didn't saw it myself. What I saw was the young there feeling abandoned and let down by the central and provincial government, and their parents.
more expensive than chinese
as for salaries - yes indeed they are up. not every chinese laborer is a slave obviously, but many are - not usually for electronics directly though, more often for the inputs of such (energy and what not).
i'm surprised there's contention about this - it's all over the news.
How much more expensive? 5%? 50%? 200%?
