I would say both yes and no. I would lean towards yes, like some have said with all the crazy lawsuits and stuff. But in some respecets it's not as bad. Lately I've been reading Lone Wolf and Cub, which is a manga about a ronin assassin in feudal Japan. It tries to accurately capture that historical context. Anyway, it makes me very grateful that we no longer have a formal nobility class. If someone was of the high up nobility, and you were a peasant that failed to bow to them and address them with every respect, it could be taken as a greivous insult. It was insulting to talk to them as if they were a regular person, like you do everyone else. And if you insulted their honor enough they could have you lawfully put to death. I'm so glad thats over with. It's not like I like to go around insulting people, but I hate it when people get offended when you treat them like a normal person (as opposed to worshiping them as a demi-god). I suppose there are still people that still think that way, as if they are nobility. But the difference today is that even if they think that, there is no laws or rules that force you to agree with them and act as such. So there may still kind of be nobility mentality, there isn't an official nobility. If you say "sup dude" to the president, instead of "greetings your highness" there is nothing he can do to you but complain. Even if you directly and intentionally insult the president he's not going to take you to jail or demand you kill yourself on the spot.
