Being such a specific topic...
The only one I can think of now, is (maybe) "The International"(?)...
(http://www.imdb.com/title/tt0963178/) Although, this is a movie more about
the banking system, than the capitalist mode of production (with which it is
very much intertwined)...
(But, beware that some of this movies appear, a lot, to have so-called
"predictive programming"/"subliminal elements" in their arguments... ;) -

In this present day, I think that the problem people should be alerted to, is
not "Free-Market" Capitalism, any more. But, Capitalism in its
Corporate/Fascist form, instead - which is the one we increasingly have, in
terms of Economics. (And not only...)
People cannot afford to mindlessly spend money, any more. Since, most of them
now simply don't have the money to do that - due to the fact that the Economy
is being destroyed *on purpose*, in order to save what's left of precious
(and scarce) natural resources for the elites

(So, the "problem" of people wasting natural resources on things they don't
really need is already being "solved"... In the worst way possible...)
