So ...Greece is running out of many pharmeceutical drugs, partly because big pharm conglomerates cannot get such a big price there, (although they could still make a per unit profit on them there), but mailnly because of their fear that middlemen in greece would sell them onto/in other countries where they could get far higher prices undercutting the going rate in those other countries, thus devaluing the prices in those other countries and affecting the pharm congloms profits.

Of course, some bodies could try to make it illegal for middlemen to do this, but I guess capitalists would hate this would be regylation on markets and purist capitalists sometimes pretend that capitalism should just be set free to do its own thing and everything would be OK
