The problem with this is that the wealth of the rich wouldn't pay for much earnings.

I mean people complain about medicine as well. And then you check. If we fully nationalized all pharma, and put their profits at zero (but kept development going) ... that would mostly be a 10% drop in the cost of medicine on average at most (more like 2-3% for the really common ones), 20% for some of the more expensive ones and there would be the exceptional medication getting 25% off.

This is not the price reductions for medicine that people are looking for when they're complaining ...

I suspect this is similar. If you redirected all profits to employees, it would be those sorts of numbers. 10% more. 20% more, with 30-60% of the increase going to the state. 100% and more increases would be limited to some companies that are already paying pretty well, like Google or Facebook.

So this simply does not provide a solution.

What study supports your claim that a nationalised pharma industry could lower prices at most 25%?

Do you know the cost of insulin in the USA and its cost in the EU, although being both private companies?

INSULIN is bloody cheap. You want the old bovine insulin in common use 15 years ago, and still in use in much of the world? You can get a bucket of it for ~$200.

Re-inventing insulin the way people want it to work:

1) adaptive. Currently means combining making minute quantities work perfectly, but slowly, which is, of course, a total contradiction.

2) VERY long lasting (which is of course also a total contradiction because the dose has to vary)

3) Keep developing this further, oral application, but at some point totally adaptive without an implant would be excellent.

4) without using animals, or even animal cells (even though that doesn't really matter)

5) oh and without using cancerous cells, which is the other trick we know

6) so in essence using the newest, most expensive, most patented trick we know, "yeast expression"

7) using the most expensive protein purification tricks we know

THAT is expensive. And, uh, well of course it is. Now, I get it, the best treatment is the best treatment and the most expensive one, and everyone should get it, and of course doctors will advise the most expensive one, for good reason. But there's currently various compromises available too.
