That's true but we don't want businesses to abandon health insurance as a perk altogether. If they did then all health care would be through government programs, which would bring the controversial benefits right back in again.
RE: If they did then all health care would be through government programs
What about PAYING FOR YOUR OWN HEALTHCARE? Why does it have to be a government program?
I suppose your scenario is most likely ( i.e. single payer ) But a system for health insurance that eliminated the employer and made health care the responsibility of the individual ( not the government) would be a good thing.
