It's complicated.
Market infrastructure, rights of way, education, air, justice: 100% public
Food, water, shelter, power, healthcare, security: 80%/20%
Communications, textiles/clothing, pharmaceuticals, research, journalism, tools/machines: 60%/40%
Artistic patronage, vehicles/transports: 40%/60%
Tourism, amusements, restaurants, conveniences: 20%/80%
Religion, luxuries, fashion: 100% private
@Radical_EgoCom The more necessary a thing, the more of it should be publicly owned, low or zero profit margin, and controlled by democratic or consensus processes. The more unique, specialized, or unnecessary a thing, the more of it should be privately owned, unlimited profit potential, and controlled by a few visionaries or even a single mad tyrant following inscrutable goals.
That way, we can have weirdos doing innovation and whatnot, but they can also fail without making a big crater.
