Srila Bhaktisiddhanta Saraswati Maharaj is quoted as saying this human society (referring to modern society) is a combination of the cheaters and the cheated. Maharaj also is famous for saying that this material world is not a fit place for a gentleman.
Therefore, the only way a man can live "happily" in this world is if he is blind, ignorant and selfish or if he is a cheat himself. If a man is blind to other people's suffering, ignorant to the real problems of this world and selfish always worrying about his own needs and wants, then such a man can successfully and happily live in this world. Otherwise, the only other option is to cheat himself.
Any sane gentleman with an ounce of self-respect and gentlemanliness cannot and will not tolerate the modern day society of living- so much quarrel- so much hypocrisy. Therefore, the only recourse for such a gentleman is to become Krishna conscious. Krishna conscious means God conscious!
