According to Pat, when GM exports parts for assembly in Mexico, that's bad.
I wish he'd make up his mind.
Actually a correct summation of Pat's points would be when dell assembles imported parts in the uSA that is bad compared to assembling parts made in teh uSA in the USA. When GM exports parts mostly from Vountries other than the USA to Mexico for assembly there and later sale in the USA that is worse.
At least that is the clear implication from what is written.
Your interpretation is incorrect.
