Yeah, that's why that's a career for many people. Because most of us don't have the ability or skills to do that, so we pay someone who does to do it.
Why would I subject my mother to my shitty care, when I can pay a professional who has trained and worked with elder care their entire life who is really really good at it, and therefore she has a WAY higher quality of life in that home, than she'd ever have with me? She's be utterly fucking miserable living with me and me with her. I also literally don't have the time to be changing her diapers 6x a day, because I have a full time job and other responsibilities.
But right, anyone who treats their parents well by giving them excellent elder care from a professional is a fucking asshole, right. Why not force her to sit in her own shit 10 hours a day while I'm at my job.
