The working world, when it was male dominant, was 100x more fun to work in. Guys could "shoot-the-shit" with each other, say whatever they wanted and competitiveness was seen as fun not as "toxic". The work environment when it was male dominant made people better because the men would compete with one another and strive to improve. Work was actually a lot more "fun" and in some ways it was a "safe-space" for men to get away from all the drama and toxicity that existed in their personal lives.
Women have utterly destroyed the workplace. Men's lives are inarguably much worse with women in the workplace. Nothing good has come of this.
When you mentioned competition it made me think, to be honest I really don't try anymore at work. Not that I do a bad job, but being I'm in the corporate world there's really zero incentive to push yourself anymore. Simply being decent is above average anyway and when you get to a certain point you're really blocked out of advancement options. Not that I'd even want to advance to that anymore because at that same threshold everything about the job becomes political.
Like the other said too, women's lives are worse off as well. If I were to think about women I know who are the happiest, the whopping two women I know who are stay-at-home mom's for the most part would definitely be very high on the list. I'd not even say it's because they get to sit home and be lazy all day. The women put in the competitive environments just aren't cut out for it. Men can compete with each other one minute then go have a drink with each other the next. Women are too cutthroat, their competition becomes a part of them and they can't let it go. Their nature is to not allow them to disconnect things it seems.
