Ya know folks, we already have mandated Health Insurance for all employers with common law employees. All employees are covered and the policy covers Health Insurance, Disability Income Insurance, and Life Insurance. And in most states there is a Government Option which competes with private insurers. Owner-employees can participate if they wish. What is this plan called? Workers Compensation. It is not federally mandated, is slightly different from state to state, and rates are based on the nature of the business risk and experience of the group. And, for the most part, employers are not liable for most work related accidents, injuries, or deaths.
Here's my suggestion for health care: Superimpose non-occupational Health, disability and Life insurance on existing Work Comp. Mandate each state to develop, with its State Department of Industrial Compensation, a formula to integrate all non-working, legal residents, within their jurisdictions, for Health, Life, and Disability Insurance. Then, invite bids from the carriers doing business in each state, with the Federal Government providing catastrophic stop-loss coverage at some predetermined level (Like $250,000). State Compensation Funds will compete with Private Insurance companies---as they do now. Employees would pay the premium for the superimposed coverage, and non-employed legal residents would pay the premium stated by the company, or the State Fund, which ever they choose, for 24 hour coverage. Insurance Companies, which are supervised by the states, are free, within reason, to set rates and still earn a profit. Individuals are free to select the Doc/Hospital of their choice. Treatment options would be determined by the insurance company, but an insured is free to shop companies. As in W/C, all are covered on day 1 and pre-existing ailments must be covered. Tort Liability would be the same as industrial compensation, as regulated by the state.
I know this may sound convoluted, but I think its workable, would provide for regional differences in risks, occupational hazards, and income levels.
