Ezra Klein explains why Obamacare is a good thing. Quick summary: Under the old system, it was too possible that you'd lose your health plan for a myriad of reasons outside your control (including rising prices) or might not be able to get one in the first place. If and when the Affordable Care Act is fully implemented across the country, you'll always be able to get a new, affordable plan. They may still have to tweak a few parts of it to make that happen but at the moment, that's where we'll wind up. The alternative is the old system and millions more who can't get or afford decent health insurance.
