And it works for life-saving drugs too:
Health minister Simon Burns blamed dwindling stocks of potentially life-saving asthma, cancer and diabetes medication on companies selling to lucrative export markets.
Now I'm guessing that those exported drugs aren't being used to make pasta sauce or children's toys but are used for their life-saving purpose. So the number of people made better by the drugs hasn't changed, just that fewer of them are under the NHS.
That's what comes from fixing prices, Simon. For heaven's sake, you're Tory MP, you should know this stuff!
