China produces stuff for much cheaper than the USA could.

China has access to plenty of high-demand minerals both domestically and through agreements with other countries ( especially in Africa ).

Lower labour costs, more workers, less civil unrest, no blacks and browns ( the % potential pool of actual worker is higher ), copying other's tech and software, less knee-caping regulations, less environmental protection, etc.

They are also alot more willing to cut corners on quality and then adjust based on feedback / recalls / fines with the least costly fix. For all the bad things comming out of this, some pretty efficient manufacturing comes out of that too.

Would you buy a $5 cable with a 0.5% rate of defect, or a few $0.5 cables with a 2% rate of defect? They will do exactly the same thing if your cable isn't a faulty one.

You can't compete with that without extensive protectionist policies.

Oh and it's likely an item ''made in USA'' is assembly work done with parts made in China and Taiwan.

So of course China is taking-over.

Never forget that Demographics is Destiny, thus the USA and Europe are doomed to becoming third-world shitholes unless we reverse the demographic vandalism done to our countries.
