Just like piracy, it doesn't work that way. Far more people are willing to pay $10 for a selfie-stick phone case than $50.
Alternatively, I've also seen a lot of Kickstarters which were simply "marketing" for an existing yet not-so-well-known product available from Alibaba, with a substantial markup added. This means there is already significant "innovation" happening in China, contrary to what a lot of people think --- they just haven't seen the true scale of what manufacturing in China looks like.
