I set up a Type C corp for my business. With it, the company can pay for all my employees (just me and my wife) medical expenses. For health insurance, in NC, I pay out the nose: $1,200 a month. It's a good, but not great, Blue Cross plan. In NC, that's really the only company that will look at you.
600$/month pretax is not that bad, but I suspect you can do better. https://www.ehealthinsurance.com/ has lots of plans starting at $264.45 /month for a 35 year old.
Granted the deductibles look high, but unless you have ongoing heath issues your generally better off using a higher deductible and putting the difference into a savings account.
PS: Don't forget the high ROI part of health insurance is simple negotiating power, the risk mitigation part is less useful.
