Fair point, I'm sure it exists everywhere. Free riding is never going to completely disappear (psychopathy seems to be evolutionarily stable after all). But when you look at the outcomes of the Public Goods with Punishment game in the link, there's definitely more free riding happening in the poorer countries studied. Maybe weak institutions and proximity to starvation result in a greater percentage of this behaviour in the population? The causality is tricky to figure out though.
