Personal experience can mean a great deal in how you look at policy.

It's not a well known fact, but Chief Justice John Roberts has a history of epileptic seizures. He suffered one in 1993, and again in 2007. That's not very frequent, but it's enough to trigger concerns, and probably to get him on anti-convulsant medication. Of course, that's no problem for him. SCOTUS judges get excellent healthcare.

But, if he hadn't had the fortune to go to law school, become successful, and be appointed to the Supreme Court, he wouldn't have that healthcare. If his degree were from night school instead of Harvard, he might be working somewhere as a small time tax attorney, and his epileptic seizures would be considered a pre-existing condition. I'd like to think that in his deliberations over the ACA, he thought about the potential fate of that less-lucky man he might have been, and what might happen to people like him for no other reason than having one crossed circuit in the brain that they can't help.
