That is the plan, make it economical for companies to drop group health coverage. Run the medical insurance businesses out of business. By the time the penalty for companies not to have health coverage, there will be no private plans out there so the onus will be to use the government plan.
Oh, wait for them to begin taxing group health insurance benefits paid by employers as earned income. Everyone will be headed for the exits.
Goal accomplished.
The biggest mistake was when wage and price controls in WW2 incentivized employers to offer health care to employees as a way to beat the system.
Once they separated the “user” from the “payer” the system costs went out of control.
