> American companies that innovate and Chinese companies just copies.

Let's take Roomba as the example, because "innovate" does not mean what people think it means.

Roomba invented the consumer robot floor care machine and won the market early on. Roomba's competitors innovated more (iteratively adding features) and Roomba has now lost it's independence.

See Blackberry, Motorola for some more recent examples. What the lesson is: there's only one way to go when you are #1 in your market category. You cannot allow gravity to work.
