1. We should start worrying about health-care costs now--i.e., actually staff up the IPAB, encourage private insurers to start cutting specialists' reimbursement rates, and aggressively assault scope-of-practice restrictions.

2. Right now we should worry that our current deficit this year and next year and even the year after is too small.

But, otherwise, Alan Blinder is 100% correct:

How to Worry About the Deficit: (1) Don't; (2) Wait a Few Years; (3) Then Worry About Healthcare Costs.
