"[A] recent ruling by the California Labor Commission reminds us of what must be one of the worst features [of the ACA] -- the requirement that large employers provide health insurance to all employees working more than 30 hours per week. This mandate is a remnant of a 1950s economy where workers remained employed at the same firm for decades and the Internet was just a series of tubes that existed in our dreams. Ironically, the ACA insurance exchanges not only make the employer mandate obsolete, but the mandate actually weakens the viability of the exchanges by locking a large portion of the healthy population into the employer provided insurance market."
