The lemming Wikipedia entry states lemmings seek out new habitats whenever population density gets too large. Kinda fitting to the reddit migration. Also loosely related to federations in terms of multiple habitats.
I like it because it's like communal but with a limit, so not herd mentally.
I'm a bit libertarian leaning myself, but I do believe capitalism requires moral constraints on external, societal costs that are not included in market forces (e.g. environmental pollution).
In short, capitalism's greatest benefit it is also it's greatest issue: it delivers most efficiently exactly what people want, but without any evaluation whether those wants are beneficial.
