I don’t think it has anything to do with caring or not caring. Very few people can afford to not charge for their services. Someone else must be paying their bills if they work for free and it’s a luxury.

Most people have to get paid for the job performed or they’ll end up on the street and starving. I can’t expect my dentist to fix my teeth and my plumber to fix my toilet for free so why would I expect a therapist to see me for free.

Of course on occasion they might see clients for free to help them out, but as a rule it’s just not affordable and not sustainable no matter how much they care
