Add doctors and hospitals to your list, 2 percent for the former, 4 percent for the latter.
That will undoubtedly be a welcome relief as right now they are carrying the brunt of the uninsured crisis by being defrauded by people with medical needs and no ability to pay. I'm sure they'd all trade 2 or 4 percent in exchange for a guaranteed payment from anyone they are required to treat.
I think a lot of businesses will drop what remaining options they have for some employees.
