While the manufacturing jobs of old cannot be brought back because they no longer exist - they've been eliminated by automation - there could be non-economic arguments for bringing back more manufacturing (e.g. a national security argument). The Biden administration did actually do that; the Trump administration is actively harming manufacturing with its exceptionally incompetent and stupid tariff policy (a very different tariff policy could hypothetically help manufacturing, but economists will tell you that subsidies - along the lines of what the Biden administration implemented - would be more effective and cause less economic harm).

The bottom line is that, on the economy, as in health, what most characterizes the Trump administration is an almost unbelievable level of stupidity and incompetence, and it will achieve none of the positive economic goals it purported to pursue (and is likely to achieve the opposite). This means that the only intended change this administration is bringing about is the Orban-style consolidation of power and authoritarianism, and a reduction in education and research.

If you want to look at things from a purely cynical point of view, that parties seek to "manufacture" voters, with the current dominant polarization axis, Democrats' clear interest is to have more educated and/or informed Americans, while Republicans' clear interest is to have fewer.
