Michael Medved is a very smart and level-headed guy. I don't think he's spewing out BS, toeing some line, or being some kind of corporate tool. He's speaking from his own experience, most likely, which is not necessarily anywhere near the "average" experience (if there is such a thing).
In that light, I'll speak my experience, which is different from his.
Most (but not all) jobs I have had included some form of health insurance coverage. The quality of the coverage has varied in terms of physician choice, how much I pay out of pocket per paycheck, deductibles and copays. In every case, I had no *choice* as to the provider, but some choice for the plan (historically, either an HMO, POS, or PPO). I have never looked for a job and based the decision on joining the company or not merely on the specific insurer, but have asked about out-of-pocket (per-paycheck) cost to me.
No employer I have had has offered to me to forego company-funded coverage in exchange for cash. Some have offered some payment if I decline coverage, but usually not. So really there is no "choice". I take what I get from my employer. If I don't like my coverage, I can "choose" to decline it and pay on my own and lose a few hundred bucks per semi-monthly paycheck.
So, no, there is not much "choice" even if you get company-supplied insurance. Unless, of course, you are rich enough to buy whatever the hell you want.
When I have bought insurance, because it was not covered by my employer, it was costly, and there was little choice (not many companies in WA state will allow you to purchase health coverage on your own), and you have to jump through hoops to prove you have been insured up to the present, have no preexisting conditions, etc, etc, etc. Cost for a family of 4+? At least $800/month (depends on the copays and deductibles).
Over the past years I have noticed the general trend is for higher copays, and deductibles, and employers having trouble keeping up with the increasing costs of insurance they provide to employees due to premium increases each year. It is definitely not sustainable for long.
