Its not in the interests of the monopolist to put their suppliers out of business.

They can set up non-profit-driven suppliers, but it seems probable that normal for-profit suppliers will flourish.

Do you mean the monopsonist? I am not sure that I would define the governments who provide drugs to their citizens as monopsonists or monopolists outside of being monopoly suppliers to their own subjects.

I agree that the 'internationals' who control domestic drug consumption have little incentive to set up their own drug production systems, but if my supposition is correct, they need the US to keep paying higher prices for the same drugs.
