>NO mater how much robots you put to screw a screw, you robots can't compete on cost with Chinese.
This is wrong. You can't compete with the Chinese on flexibility and responsiveness in manufacturing. Well you could, but you would have to get a lot better at it and have the government on your side. The Chinese chose to be good at manufacturing and in particular contract manufacturing and they have a large infrastructure dedicated to that. Chinese labour costs are lower than the US, but that only counts for labour intensive manufacturing.
Cost is one thing. Dealing with a million other crappy things is also a differentiator. My wife gets yarn manufactured around the world and imports it to be sold in yarn stores. It is substantially easier in terms of red tape, to get it made in China and import it than it is to get it made in Washington state and delivered to an address in Oregon. Also, the best makers of bamboo yarn are in China so it's not question that we would get that made in China. It's work to get them to manufacture to our packaging standards and in configurations that work for US markets, but that's easy compared to dealing with the tax departments of 50 US states. The highest quality yarn maker in the world is in the UK. Their stuff is costly more due to shipping from the UK than from the cost of manufacture. I've seen their factory floor and from processing incoming unprocessed sheared wool, to spinning to coning or balling involved 4 people.
