> Is there a practical way to administer democratic worker ownership, without centralized control?

Commonly called anarcho-communism or relatedly anarcho-syndicalism (this being actually more of a mechanism to get to anarcho-communism)...

Anarcho-syndicalism looks like you form a union, that union then builds companies that are their own "entity" but pool resources/revenues. Workers, and consumers of the companies are linked to the overall union, and can petition for things like medical bills, etc to be paid. The union could grow and grow maybe it builds a total Amazon competitor, maybe walmart too, and convenience/gas stations.

All proceeds belong collectively to all in the union, all Top level staff might have a max salary of 500k or better yet, 10x the average worker salary, so keeping worker salaries high increases wages.

The unions could as it grows seek to buy up hospitals, and other parts of healthcare systems, and run them like a normal company just with different organization. It'd basically be like Kaiser Health where it's the insurer and hospital and pharmacy and maybe even manufacturer of drugs.

The insurer part could even build out programs to basically make states Medicare/Medicaid easier to manage...

So all these related/syndicated/union companies are non-profit, extra proceeds would go towards: expansion of syndicates, mutual aid, and left over would be paid out to workers/consumers. Each worker would get a share, each consumer spending over 1000k per year would get a share. Workers could get 2 shares by being a worker and consumer... Shares would grow, so longer-loyalty === more shares.

The share is your % of revenue from the pot, so say 33% goes to expansion, 33% goes to mutual aid and 33% goes to UBI type payout, you'd get a percent based on shares you own. Philanthropic people who don't need the money could opt-out as well if they did acquire shares so their portion could be re-distributed to those who have more need.

This creates a situation where healthcare is ran by a central/quasi-power structure aka the syndicate, but it's separate from the government and it's worker-owned with shares also being used like shareholder votes on things...

It's basically a non-statist form of socialism. Another term is libertarian socialism, or left-libertarianism, but it's totally different from anarcho-capitalism or right-libertarianism.

You'll find a lot of people who might lean left or be DSA would really support this... I think a weaker central govt is good, maybe even making states have their own militaries that the fed "conscripts" when there's mutual agreed threats, and the governors would be the senate.. the fed would just govern international stuff, and interstate commerce. States would be more in control, and even cities would have more power than states and majority of taxes would go to county, state, then federal... maybe like 50%, 30%, 20%.

That's how my ideal society would look. Eventually the healthcare union syndicate program could roll out nationally for everybody, and maybe be subsidized some by the government for those who aren't officially "customers" but as we grow we'd have so many competing businesses it'd hard not to be a customer for one of them...
