When did he say his life was miserable? All he's saying is that the system is bad and there have been no real changes to it whatsoever. What is this smug schoolmarmery? You're purposefully misinterpreting his words and insulting him personally, why? Are you even trying to convince him of something, or do you just feel like antagonizing him for the hell of it?
If he is deeply unhappy with the country's current state, it's perfectly reasonable to both want it to change for the better, and also be willing to flee to what he perceives as greener pastures. It makes no sense to imply that these are mutually exclusive positions.
This is just an unhinged thing to say. What do you know about his personal life?
