It's the frog in the boiling pot of water. It all happened so slowly that no one realized there was a top-down coordinated effort from the Chinese to steal as much as they could in any way that they could and claim it as their own.
Foreign companies let their own greed blind them to the fact that the Chinese take the idea of synergy to an entirely different level than what they know. They were limiting their think to their own corporate structure, but the Chinese look at eveything on the national level. The idiots that thought they'd be saving money using cheap Chinese labor are now finding themselves muscled out of not only the Chinese market, but their own domestic market with the entire communist apparatus working against them.
At least people have woken up to this, though serious damage has already been done.
