I don't agree in any way. In fact, it's normal to love others much more than you love yourself. This is easy to understand if you have parents or children.
Way more. I love my siblings more than I love myself. I love my friends more than I love myself. I'm not good at self love and self care, but it's a bit easier if I tell myself that I do it for them.
I'm not sure I understand your point. Is it children staying home because they love their parents more than themselves and want to be with them? Or because they know their parents want to be with them and thus they prioritize their happiness? Or something else entirely?
