We Spend More Money When the Money isn't Our Own

  When we spend another person's money, we spend more than if we spend our own. That's a principle of economics.
  As our nation looks at the high price of health care, we should notice this principle at work. As long as the insurance is in place, covering the bill, we aren't careful about the expense. We should be, though, for eventually the insurance companies pass along the expense to us, charging us higher premiums.
  Is having a system based on insurance a good thing? I think we should give it thought.
