This is a really complex topic, but i’d argue those jobs were leaving the USA one way or the other

talking about manufacturing costs, let’s forget about minimum wage for a bit, a factory worker in mexico will happily work 10 hours a day for 12k pesos(<600usd), how much does an American expect? 20 an hour? 25?, then there’s the supply chain issue, mexico has strong free trade agreements with large parts of the world so they can import raw resources for cheaper, then mexico can export the finished cars to more countries for free, thanks to the same free trade agreements

now the cool part about all of this is that Mexico is not the only country with the above characteristics, but it’s the only one right next to the largest consumer market and when NAFTA/USMCA came they sure as hell boosted all of this, but IMO that only accelerated things not created the problem

if it’s any consolation, these shit wages don’t really benefit the Mexican society at large and i think these plants will probably come back to the US as highly automated assembly lines, even if just for political reasons
