A single-payer system could actually allow coverage of those services whether it is a dietitian, a personal trainer, etc. Problem is, most health insurances do not cover those things. Also screwed up is the whole "you need a referral" to see a specialist. I can guaran-damn-tee you I know more about my body than my doctor. after my 1st torn ACL, I started self-referring myself to the orthopedist who I trusted when I knew there was something my doctor would tell me I needed to see an orthopedist for. You know what having to see my primary care physician first when I broke my wrist got me? 16 weeks in a cast with little to no healing (and the doc knew this) before he referred me to an orthopedic wrist/ankle specialist who then told me I needed surgery because said bone in wrist doesn't have an adequate blood supply and rarely, if ever, heals on its own. So, 6 more weeks in a cast/brace post-surgery plus needing to use a "bong growth stimulator" for that period of time as well to ensure the bone healed in addition to the screw they inserted to hold it together. So, 4 PCP office visits, 4 sets of xrays BEFORE I ever got referred. Sounds like a waste of money to me.
