My teachers have talked about how critical and fast to complain this generation is

Your teacher's generation was just as bad. At least this generation only complains online instead of standing in the middle of the street with signs causing real issues.

I'll take the whiners I can ignore than the ones that block traffic or start fights with police (I'm sorry but I've seen groups with equally pointless issues cause problems, I'm not talking about the people with legitimate issues picketing).
