"Explicitly chose" is a strong word.

US and China are on completely different stages of industrialization: The US had its massive boom of manufacturing almost a century ago, enriching its population massively. Those rich citizens make the same manufacturing uncompetitive today, because no one is going to work in a factory for $20k/year (median wage in urban China), when he can work for other "rich" people for more than twice as much.

Switching paths is not feasible for the US in the same way that it is not gonna be feasible for China to hold on to all its industry as wages rise: You can't compete globally at "poor people wages" while being "rich", as simple as that.
