While many full time employees will find employer provided insurance their best option, it can have substantial drawbacks. My employer policy is reasonably priced for the employee, but a family plan is $700 /month with a $5000 deductible and $8000 out of pocket max. The provider network is also small and omits several area physician groups and hospitals. This is not uncommon for smaller companies.
The exchange plans are just as costly without the subsidy, but at least it gives options to those who are self-employed or who find the employer insurance less than optimal for their circumstances.
Note to those shopping for insurance, in many cases you can go directly to the insurer and price or buy insurance. The prices are probably the same, but at least the insurers website should work. Also, there are private health plan comparison websites that still exist and are selling 2014 ACA compliant plans.
