And like any other skill some people are more gifted in learning that skill than others. Anyone can learn to paint, but not everyone is going to be a Monet or a Rembrandt.
Everyone doesn't need to be a Monet, they just have to be able to paint their name on a poster without embarrassing themselves and putting down others.
Everyone can paint their name, that is a 0 skill exercise. And I wasn't saying everyone needs to be a Monet, more that these are high ceiling skills you are talking about and there is a lot more variety than is given credit.
There's room to go really really far down that path and even become a licensed therapist if someone takes to that kind of work and is looking for a second career, but in this analogy, some people don't even have the EQ to be able to paint their name with fingerpaints. Maybe I've had more misfortune dealing with difficult people though.
