> We don’t have the infrastructure to manufacture
That's trivially false given we're the second-largest manufacturer in the world. We just don't want to employ people, hence why we can't make an iphone or refine raw materials.
The actual issue is that our business culture is antithetical to a healthy society. The idea of employing Americans is anti-business—there's no willingness to invest, or to train, or to support an employee seen as waste. Until business can find some sort of reason to care about the state of the country, this will continue.
Of course, the government could weigh in, could incentivize, could subsidize, could propagandize, etc, to encourage us to actually build domestic industries. But that would be a titantic course reversal that would take decades of cultural change.
