You're applying that too broadly. Sure they lack more power than what they desire in a cog, who doesn't. No excuse for being inebriated at work.Blaming teachers for the fukked up education system is like blaming low-level drug dealers for the overall drug problem.
In fact, it's even worse to blame the teachers, because most people get into teaching thinking they can change the system. After years of being shytted on from every direction, and being ymade to do all types of bureaucratic shyt, people become rightfully jaded.
If you truly believed that then there's no way you can object to what this student is saying because it means they're in the system as well, so their behavior should be excused too. Why can you explicitly acknowledge it as poorly arranged system, but they can't?
