You can guarantee universal healthcare (and medication) without top-down control of pricing, or at least not total control. Most drugs aren't making headlines, so you can control the x% that matter while still getting cheaper prices for most consumers by letting the outlets compete.

Your website suggests you are American, so I recommend taking a look at the various healthcare systems on display in Europe, they're not all made equally (i.e. Some do more on behalf of their citizens than most). In my experience of watching American discussing healthcare in the EU, the subtleties are often lost, sadly.
