The fact that most Americans get their insurance through work is a historical accident: during the Second World War, wages were frozen, so companies began offering health insurance instead. After the war, attempts to create universal heath care were stymied by conservatives and doctors, and Congress gave corporations tax incentives to keep providing insurance. The system has worked well enough for big employers, since large workforces make possible the pooling of risk that any healthy insurance market requires. But small businesses often face so-called &#8220;experience rating&#8221;: a business with a lot of women or older workers faces high premiums, and even a single employee who runs up medical costs can be a disaster. A business that Arensmeyer represents recently saw premiums skyrocket because one employee has a child with diabetes. Insurance costs small companies as much as eighteen per cent more than it does large companies; worse, it&#8217;s also a crapshoot. Arensmeyer said, &#8220;Companies live in fear that if one or two employees get sick their whole cost structure will radically change.&#8221; No wonder that fewer than half the companies with under fifty employees insure their employees, and that half of uninsured workers work for small businesses or are self-employed. In fact, a full quarter of small-business owners are uninsured, too.
