Except that the average pay per machine worker in the USA is about 32.5k and in Mexico it is under 5k. The entire reason it was shipped over seas is because of lower labor, material, property, and regulatory costs. Not just labor. If we bring it back to the USA all of that goes up. If we bring it to Mexico it actually goes DOWN. It helps solve immigration issues. It would help to break up gangs by offering saner alternatives to young people.
There are a ton of down stream reasons for it.
So you seem to be saying labor and cost are not the thing just incentives from the government? I don't agree but if that was true then the CHIPS act should have solved it and it hasn't either. I think it is all of it, and unless we push incentives for secure locations with reasonable regulations and labor markets it just won't work.
The truth is Americans by and large don't want to do these jobs...they want to do service and computer jobs mostly. So we should be pushing that.
Major factors in deciding an international company's high tech country are taxes and capital costs. Taxes are usually between 60%-90% the total expenses of any company, while big capital expenses always carries a risk factor and most companies prefers to just play it safe (continue doing the same they always do) at the face of no help after a given scale. Property, wages, materials and regulations are secondary or close to irrelevant other than avoiding extreme scenarios.
For US companies, usually the US is already very favorable, and in fact the immense majority of works are generated by, well, US companies, for US workers, in the US, contrary to any myth. Taxes are among the lowest in the world and state governments nearly 99% of time offers further support like in gifting the land or providing materials, electricity and what not. Silicon Valley itself pays virtually no taxes to California, for example.
So, what makes US companies occasionally make some (not all) investments outside? Well, because they do direct conversations with other countries and ask them if they can offer them conditions that are even better than in the US, for example Costa Rica exempted them from ALL taxes for 15 years + land gift + material provision, and are just now charging a small amount, with Costa Rica preferring Intel to help them with education and charity services to increase the expertise level in the country. Sure, lower wages are a plus, but ultimately no taxes is going to move anybody to press yes.
Or China, which literally covers 51% of your capital investment, that literally allowed multiple companies to double their capital return rates until conditions tightened recently. Or Ireland which is a tax haven. Or Israel which assured to cover a large part of Intel's capital costs. Or Germany which literally gave 17 billion Euros to Intel to build a fab on Germany.
So the CHIPS Act came as an action to replicate the same, so Intel would get tax benefits and capital injections in exchange to build two extra mega factories in the US, alongside many of the ones they already have. And, Intel is actually building them, albeit with some delays (if anything, due to the government failing to comply with their part of the agreement and Intel literally not having more capital).
And, it is not like republicans doesn't have intentions to have those two factories built. It is just that instead of incentivizing Intel (or other US companies), they prefer the approach of just force them to do that "or else" route, which in all honestly is fair since they helped in building those companies to start with, and any profit will remain for them anyway.
But it looks very poorly on the government to take one action and then sabotage it and take a different one later, seriousness is a lot of times more valuable than any tax break. Republicans should have thought this better before approving CHIPS in the congress to start with, and both Republicans and Democrats should coordinate better stuff like this, so policymaking is less susceptible to election cycles.
AMD by its part started with much smaller capitals, so they never managed to make a competitive foundry, so they have always just brought the best from any foundry available. TSMC is that one today, after the Taiwanese government poured astronomical capitals and benefits and education and other stuff to make sure it would grow, and it did indeed grow, and it is now attracting capital from the whole globe and running by itself and the gov is profiting back from it.
Now personally I do not believe Intel needs more help from the US government specifically, yes, but I am just explaining a bit the dynamics of what makes high tech companies pick the countries for their investments. Other fields (like lower-end manufacture) definitively flocks to cheaper wage countries, and others flocks whichever regulations are the weakest and so on, depending on their activities.
