In many latin cultures it is a matter of pride (not shame) to fool or cheat someone. Looks like the latins in this complex are doing it on a big scale. I am not surprised.
Well they and Barack are on the same “fool you” team.
One of my Mexican coworkers told me that very thing. He said "in Mexico, it's do to others before they do unto you." They take pride in screwing each other over.
They bring that value system with them when they cross the border. He doesn't trust his fellow latinos to be honest.
