Reinventing Socialism from first principals

Still perverse incentives. In this case the government is implicitly biased against startups competing against a giant.

I read recently that corporate taxes used to be a lot higher on large conglomerated companies, which used to deter monopolization somewhat. Under this automatic-stake idea, it'd be interesting if the government's stake in corporations increased as they got larger? Companies try to avoid this and so don't combine so much?

Of course once the government does have a large stake in the largest monopoly-like companies, it's immensely motivated to keep them large. Hmm. This idea isn't good.

I agree that corporate taxes are not working at this time for one specific country. But the claim of "corporate taxes don't work" is much more broad and not something I've seen specific evidence for. My understanding was that historically corporate taxes have been extremely effective, even if those taxes aren't paid the profits of a company are instead redirected as other investments.
