I'm not saying your wrong, but shuttle software and even ATMs are different from Obamacare. The former has specific operational requirements that are relatively clear. Health care by contrast is a clusterfuck of legislation piled on top a multitude of tangential legacy systems. I don't doubt that the talent to get it right exists, but it requires more juice than just an engineer saying "this thing won't fly". The problem is that legislation is itself code, but it is written by people who have no nuanced knowledge of the downstream implications, and perhaps more importantly, no incentive to ever refactor.
