Since health benefits were introduced in the U.S. marketplace in the 1940s, they have been both a blessing and a curse. No one wants to be without them, but few of us can afford to pay full freight either. Most people get health insurance through their jobs or are covered through a family member's insurance. This is called group insurance. Group insurance is generally the least expensive kind. In many cases, the employer pays part or all of the cost. Some organizations offer only one health insurance plan and others offer a choice of plans: a fee-for-service or indemnity plan, a health maintenance organization (HMO), or a preferred provider organization (PPO).
