Nationalizing is unlikely to increase productivity and innovation.
There’s multiple competing goals here and we need to think about how to achieve them.
If we think that Intel is fixed and unlikely to need to change, perhaps nationalize and then just operate it as it slowly declines. But that’s also going to make other chip companies less likely to invest in the US as few investors want their investments nationalized.
The purpose of these economic investments isn’t primarily moral justice (although I think that should be part of the calculation). The purpose is to increase US chip production.
It seems quite silly to think that nationalizing Intel would lead to greater US chip production.
