> I don't really want universal healthcare but I would take it if it makes people stop talking about the obligation of employers to provide * additional services and benefits for their employees that fundamentally have nothing to do with the labor/payment relationship.

Employers don't provide additional services for altruistic reasons: having perks outside of the "labour/payment relationship" is a tool for attracting and retaining employees.

That said, basic access to healthcare should not be contingent on employment (with a specific company) because it gives companies a significant amount of power over their employees. Many companies abuse this to trap employees into unfavorable working arrangements.
