We have a single-payer system - Medicare. ACA is just a jobs program for the insurance industry, perpetuating 2 types of bullshit jobs: medical billing and medical underwriting.
Medical "insurance" companies actually don't do much underwriting any more. Most policies are self insured by large employers. The insurance company just manages the provider network and administers claims.
Even medical billing is gradually going away with the shift to value-based care and accountable care organizations (ACOs).
