Opt-Outs are popular

Yesterday it was announced that airline pilots are special and will soon be able to opt-out of humiliating nude-o-scopes or gropings at TSA checkpoints (congrats to them btw). They join members of congress and many other government employees who are special enough to opt-out of this administrations policies. Will flight attendants be next? Oh, and apparently Muslim women may be able to opt-out of the groping - they can grope themselves and then have their hands tested for explosives residue (details of this policy aren't clear).

Obamacare was supposed to be the great equalizer. Everyone on the same plan. Yet McDonald's and a large number of unions have been given permission to opt-out of Obamacare. By some estimates as much as 21% of the U.S. population has been given an opt-out for Obamacare. If it's so great, why are all these opt-outs needed?
