why hasn't the REST of the US business community taken the health insurance system to task as fucking with their business? The costs to other firms of the US health system look absolutely unbelievable to me.
A big part of this is that typically those on or near the top rung of the corporate ladder have the most health problems. Consequently, they want to buy *the best* healthcare they can. And, of course, not wanting to purchase anything that isn't a tax right off for them, they purchase that through their biznesses. We do have some modest laws here that, in essence, lead to "what's good for the goose..." reasoning. That is, if the fat cats at the top want premium health insurance, the same plans have to be *offered* to the wage slaves. What typically happens then, is that the fat cats give themselves bonuses to cover their healthcare premiums and the wage slaves opt out (having no chance in hell of paying for it themselves out of pocket).
Also, as healthcare insurance costs have gone up here, wage slaves have seen their benefits cut and the majority of the cost increases hitting their wages directly (iow, wage slaves pay more and more of the corporate purchased healthcare premium themselves). The spiralling healthcare costs, then, have disproportionately affected wage slaves. And in Murica, who cares about them? As you so rightly point out, certainly not our gubbamint.
