"It's a sad state of affairs...."
Actually, that isn't the case. Not to let facts get in the way of a good narrative, but only 6.3% of Argentina's exports go to China (the top export destination is Brazil with 21%). You may find this informative, I know I did: https://atlas.media.mit.edu/en/profile/country/arg/
The picture is quite sad. Argentina's side agro out and techno in. The picture does a good job of explaining "lack of investment". The commodities boom was gift capable of producing massive internal investment that never happened. There's that "sad" word again.
