Seize (that is, nationalize) the largest 100 corporations.

I understand the case for nationalizing key social infrastructure and utilities, but what is the justification for seizing the largest 100 corporations? Also why 100 specifically?

Yeah I can’t think of any potential problems if the world’s second largest nuclear arsenal, and two largest air forces fell into Christian Nationalist control led by an erratic strongman. 🤦
