An 'exchange' would allow everyone to choose their health care insurance from a broad range of options - just like federal employees and Congress do right now - and allow their employer to help pay for it.
People would have a health care insurance policy they can call their own. They could choose one that exactly fits their families' needs and their budgets, be able to take that coverage with them from job to job and be able to fire their insurance company if it doesn't treat them well.
