How much will businesses save by not having to provide health insurance and Workman's Compensation insurance?

To be sure, they'll have to chip in for National Health Care but I think their overall savings should be around 50%. What do you think?

The best system is a single payer system because it can be paid by all working men and women through a progressive tax system like in Canada where they pay half as much for their health care and yet treats everyone! 90% of Canadians DON'T WANT THE U.S SYSTEM. 72% of Canadians are either greatly satisfied or satisfied with their health care system. http://ca.news.yahoo.com/s/capress/09071…
