no doubt having your employment being tied to your insurance is a really, really bad idea, but may I remind that state of affairs is because of a government incentive put into place by FDR.
I believe it was originally because of postwar wage/price controls, which led to employers giving health insurance to attract employees, which led to the IRS taxing health insurance, which led to Congress exempting health insurance from tax, which led to the current regime we have today, compounded by the McCarran-Ferguson Act as well as the HMO Act.
You failed to mention the context of that government incentive - World War II. And the incentive you're referring to was put in place by the War Labor Board in 1942, during FDR's presidency. http://en.wikipedia.org/wiki/War_Labor_Board
It was. But perqs proved popular with employers because their value were hidden from the employees. Thus large employers could use their negotiating power to procure health insurance for their employees at a relatively low cost. They were effectively getting cheaper labor, a huge competitive advantage. The ruse was up once health insurance costs started skyrocketing.
