You have my sympathy on all that gagajo - I know all too many people who have left teaching in recent years. Some young, very bright minds who stayed a very short time.
As for 'keeping the working classes in their place' - I see more and more how this is achieved the older I get. I watch the 'deserving poor' rip to shreds the 'scroungers' and see who actually gains from this dynamic. I see people blaming the lack of jobs, low pay, and overcrowded hospitals on immigration then ask myself who is actually gaining from low wages and why aren't those lovely profits helping to build hospitals? I'm not going to digress into the whole question of immigration and Brexit etc as there are too many things to consider and this is not the thread.
I think one thing that needs saying on this thread, is that regardless of whether some children are being unduly influenced with regard to questioning their gender, and this is something I do think needs to be looked at, I don't think anyone is saying that this influence is all coming via teachers or schools. Some is via TV and much is via social media.
I doubt there are many teachers going out of their way to reinforce gender stereotypes like, 'girls wear dresses, play with dolls, wear make-up' etc etc, but the message is out there. (ooh the power of advertising and those invested in maintaining the status quo) And many of us think it needs challenging.
