A quote from the Wall Street Journal 11-1-2019
Companies that already pay some employee health costs and have more than 50 employees would make an “Employer Medicare Contribution” to the government, a fee to be determined by prior health-care costs to insurance firms. Generally speaking, those who are self-employed would be exempt from this tax, which Ms. Warren promised would be less than companies currently pay in payments to insurers.
Somebody should tell the Senator that about 26,000 employers covering approximately 50,000,000 Americans do not make payments to insurers, they are self-insured. Their costs are based not on premiums, but on the health care services used by their workers and their families.
These employers design their plans, decide plan provisions and manage costs. There is no profit for insurance companies based on claims paid and generally their employees are healthier than the general population.
All that means that when there is one big risk pool of Americans, these employers, if they are carrying the bulk of the cost through taxes, will likely pay more, perhaps much more than they do now, especially considering the array of added benefits….. and they lose all control over increasing taxes‼️
