Throughout history, men have been expendable, or at least semi-expendable. They were the warriors, the hunters; those that took the difficult and dangerous tasks. Men were replaceable, the reproductive capacity of the women was not so much. Men did get some privileges for being subject to this gauntlet, one of them being respect. As the manosphere states, respect is what men really want.
So what about today? Men are still expected to be expendable. The dangerous jobs are still theirs. However, the message that filters doesn’t is that one big reason that they are expendable is that they are incompetent, toxic, stupid, etc. “So continue doing the dirty and dangerous jobs, then go away.” I am thinking that doesn’t sell well. How about you?
