Regarding the line-cutting/cheating he talks about.
I like to distinguish between "culture" and something vaguer, which is what type of equilibrium someone is trapped in. I started to think this way when I lived in Argentina. Argentina is very corrupt, but just across the river is Uruguay...the least corrupt country in Latin America by some metrics. Argentines and Uruguayos are culturally quite similar (the relationship is analogous to that between the US and Canada), but one country is much less corrupt. I mused about this to my Argentine friend and he said "The difference is that in Argentine politics, if you're not corrupt you'll get destroyed." (This is kind of exaggerated but it gets the point across.) So while the cultures are similar, individuals in each country find themselves in different equilibria: if you're the only corrupt person in a group, you'll get caught and ostracized; if you're the only uncorrupt person, you'll get forced out (the same thing happens to police departments in the US). It is impossible for an individual to change the equilibrium.
Likewise with standing in line: Chinese immigrants to America preserve much of their culture for a while but don't cut lines; if they did they would be called out for it, being among the few who do so. But if everyone around you is blatantly cutting, then maybe you'll do it, too.
