This is where our opinions differ. If this was 10 years ago I would agree that the workmanship was poor. These days however we are seeing good top quality products from china. In fact, I believe QC/QA is ultimately determined by the investor, not the producer. Who cares where it comes from as long as it meets the standard demanded of them? In fact, TLG doesn't even need to invest. They merely need to contract out the production to several companies which can produce the blocks to their required standards. Absolutely no risk to them. If a company doesn't produce to the required standards, fire and find another contractor. Only the key processes need to remain within the original company to maintain its competitive advantage. I believe with TLG, the key processes are product line designing, market research, and advertising. They shouldn't really keep the production process in-house.
If you really feel the mass engineers that china is producing are still subpar, there're hongkong and singapore as potential alternatives. I know of quite a few firms that produce industrial grade high precision plastics. As for worker's comp issue, while I do think $100 a month is very low compared to the US standards, $100 in china is a lot of purchasing power. It wouldn't be fair to compare what we are used to vs what the situation is over there. It's like comparing a worker in montana vs one in new york city. Obviously a nyc worker will be paid 2 or even 3 times more just because the cost of living is so much higher in nyc. If the wages were that bad, I doubt many chinese farmers would have migrated to the cities to seek jobs.
