For the modern American tech corporation? Full throated workplace democracy, with an emphasis on small d:

Corporations are the last authoritarian forces we willfully allow to dictate how we live our lives, I think anything to dismantle their power is worth pursuing. If democracy is good enough for states, it should surely be more than good enough for the economy.
As someone who is a big fan of consensus and voice, I don't see how current corporate leadership could get worse if more workers inside the company had more opportunities to direct its future. It's their future too, they need a say and telling people to just leave goes back to the neoliberal decaying value of money above all us.
At the risk of being accused of reductio ad absurdum - do you want companies to be run like American HOAs? If so, do you expect the results to be the same or different than with HOAs?
There are, if not millions of HOAs, surely at least one hundred thousand, but you only hear about the ones being silly.
It's a bit of a lazy punchline, especially because HOAs are one of the purest forms of democracy, they really only exist (barring certain corporate controlled ones that I don't think count) because the people there want them to.
