A" No, totally not. Totally not. The market clearing price is a function of supply and demand - that is all it is. It has nothing to do with 'maximizing social surplus'. Yes - it maximizes economic surplus, in the narrow context of that transaction, but that economic surplus does not necessarily reflect social good - moreover - supply and demand are functions of other things entirely. The easiest way to see this is to look at Monopolies. Monopoly players of a critical good can extract vast, vast profits. What they actually 'do' with those profits is critical to understanding total social good. Imagine a monopoly provider of gasoline to the US, that takes it's profits and puts them in a room - and does not invest it back into the economy. This is not 'good' for anyone but the owner of that monopoly. The same can be seen in rent-seeking in any number of places. Also - BTW Netflix has about 1% EBITDA [1]. Their gross margins are not that important when you figure you have to pay for 'staff', R&D, 'networking', 'advertising' :).
