How are we still okay to let ourselves be in the hands of people who don't really care?

Sometimes I really wonder if there's any incentive other than money we can offer to people who have to take care of others, from doctors to nurses, from caregivers to volunteers. Well, volunteers are getting nothing already, but what about the others? I guess to always show concern to others is hard too, considering many of us don't even do it regularly haha I'm talking about myself
