Training and credentialing isn’t the same thing as assuming that the people who end up at the top of society are there because they “deserve” it, as do the people living out of their cars.
That’s precisely what insisting we live in a meritocracy right now today papers over - that the best don’t rise to the top, because often people with talent and promise lack access to the education needed to get those jobs and if they are, they often have to deal with ingrained racism, sexism, etc. These things are not figments of some SJW imagination. They are facts of life.
No one is saying “let that guy fly the plane.” They are saying that we do not live in a level playing field with regards to access to training.
