What is not being calculated is the cost of what the average salary will climb to. Look at European countries as an example. The $2000 will be to the govt, and there will be a X% added, or demanded by workers to offset the need to pay for the govt. HC. This will decrease profits and in turn hurt business. When all of the dust settles, you will find that a lot of the large employers, will continue to supply the private health insurance.
In tough economic times, who says that large employers have to pay anyone higher wages when there are millions of unemployed and underemployed people out there who would love to have a job?
