That's the same everywhere in the developed world. If you are too poor you are taken care of through social programs(even in the USA), if you are rich you take care of yourself but if you are middle class you will have to fight for this privilege everyday.
It goes the same for the social norms. If you are poor you can have a trashy sex life and say whatever you like, if you are rich you also can have a trashy sex life and say whatever you like but if you are middle class you must have stable monogamous relationship with somebody of similar background and age(you can't just have sex with anyone between 18 and 80 and throw a scene, unlike the rich and the poor) and watch your mouth.
