For some reason I find the case for anti-trust is best explained in relation to entertainment:

Also it's worth noting that I see a lot more criticism of capatilism from (audio) shows not funded by them like Welcome to Night Vale and The Red Panda Adventures...
@alcinnz For those with some background in economics, another solid argument for antitrust and not letting any individual market participante get too big relates to how the Leontief hypothesis breaks down when one economy is radically larger than another - by the same logic it's not merely a strict monopoly that's imbalancing, but a particular market participant being large enough to affect the market by sheer relative scale.
