Krugman simplifies the argument

So all of us can understand:

Health reform made simple

Kudos to the Times for a story that, for once, emphasizes the remarkable unity of vision health reformers are showing, rather than the squabbles that are an inevitable part of passing major legislation.

The essence is really quite simple: regulation of insurers, so that they can’t cherry-pick only the healthy, and subsidies, so that all Americans can afford insurance.

Everything else is about making that core work. Individual mandates are a way to prevent gaming of the system by people who don’t sign up until they’re sick; employer mandates a way to hold down the on-budget costs by preventing a rush by employers to drop insurance; the public option a way to create effective competition and hold costs down further.

But what it means for the individual will be that insurers can’t reject you, and if your income is relatively low, the government will help pay your premiums.

That’s it. Any commentator who whines that he just doesn’t understand it is basically saying that he doesn’t want to understand it.
