Do they really? I've see only select hedge funds actually advertise their health plans. Even that is usually that "we pay 100% of premiums." Most plans are impossible to assess until you actually get to the job and see the tiers available and support available. The devil is in the details -- network coverage for your specific state, co-insurance, co-pays, deductibles, % premium paid, support like QoS/tier.
