If I say "Down with capitalism" who gives a flying fuck? However, if I write a 300-600 word essay that explains particularly well why we should get rid of the pesky thing, some people may pay attention. If, otoh, the POTUS or a US senator says "Down with capitalism" - that already has gravitas and he/she needs to say nothing more.
