China probably has more people at every level of education than Germany, they're just more sparsely distributed. So the one person with really in-depth manufacturing knowledge spends their time supervising a bunch of greenhorns who barely know how to operate the machines, making lots of cheap crap. But they're learning something new every day and may eventually become skilled enough to cost-effectively manufacture high-quality goods instead. Of course at that point they won't be happy with rock-bottom wages anymore, so it's not clear that prices will drop much.
