What purpose do personal care Careers serve for society? I am kind of confused on this question

Sometimes a person needs help with things like doing housework, getting out of bed, eating healthy, driving around, scheduling, etc.
Personal care is when that person has someone do that for them.
If we didn’t have them around then what would the people who couldn’t do the daily things in life do? If they didn’t have anyone to take care of them, what would happen? The personal care helps the people in need. Our society would probably loose a lot of people do to the fact that what they are doing is essentially saving a persons life.

Hope this helps
