Jon Cohn lays out the insurance cost savings for working and middle class families. You should definitely read the whole write-up here, but meanwhile here's the chart:
Some of these numbers are staggering -- both the repulsive costs of the status quo and the consequential savings via the reform bill. A family of four in the $48K annual salary range will see their premiums reduced from $12,000 to $3,600. That's impressive. For example, the $8,400 in savings will pay for a semester of college tuition (and then some) at a Pennsylvania state university.
