From BBC: "Mr Raab suggested it would not be in the US's interests to hike prices if "you reduce the amount, the volume of purchases".


Utter and complete nonsense, of course. A company is interested in profit, not volume of sales. The whole luxury market exists and keeps its prices high precisely by restricting the volume of sales.   

Some markets run on scarcity pricing, some on the "stock 'em high, sell 'em cheap" principle. When you have a monopoly on something, and people's health can depend on your product, going for scarcity pricing can be tempting.
