Please explain how US patent and copyright law prevents "the rest of the world" (which I assume really means the EU, because China seems to be doing just fine in their own sandbox) from developing a meaningful tech sector?
They have done very well in the manufacturing sector via IP theft starting in the 1970s.
I don't see how that's relevant to much post-2008 in the tech sector, which is primarily software driven and where China has very intentionally built their own walled garden.
