[Act] ...and you shall receive(so act good!)
The way a person (or even a country) treats you is their karma but how you react is yours.
Karma comes for everyone eventually. No one can't get away with screwing people over their whole life, I don't care who you are or who you think you are. What goes around does come around. That's how the Universe works. Sooner or later the universe will serve you just the right amount of payback that you deserve.
