A growing network of online communities known collectively as the “manosphere” is emerging as a serious threat to gender equality, as toxic digital spaces increasingly influence real-world attitudes, behaviours, and policies, the UN agency dedicated to ending gender discrimination has warned.
There are absolutely jobs where hiring the most qualified person for the job is critical. There are a lot of jobs where the threshold for good enough is far below that, and most companies are at least as concerned at getting the cheapest labor that can fulfill the position as they are at getting the best person (at that lower rate). Adding additional constraints like diversity isn’t going to affect those jobs any more than the company’s desire to save a buck.
Hiring someone over someone else purely because of their race or sex is discrimination, racism, and/or sexism.
It sounds to me like you’re talking about jobs that illegal immigrants do, especially once you brought up cheap labor. Jobs like those don’t have diversity quotas, because they almost entirely hire from the “diversity” pool.
