Companies are not blameless - it's a 2-step process. Lawmakers sold the American worker's soul to capital (companies), and the companies sold them on to China, with a fat markup.

The motivations are clear: politicians get donations and cushy jobs, the company executives get very rich due to increased short-term profits and increased valuations on the hope of establishing a foothold in a humongous growth market, China gets tech transfer, exports and a skilled workforce, and American workers get nothing, save perhaps a tiny sliver of company ownership through a 401k, if they are lucky to have one.

The reality is that China's farsighted rulers don't want to be a US client state/ colonial possession and have imposed strict rules on market participants in exchange for access to their 1.5 billion consumer market. American businesses can put up or shut up.
