You are entitled to your opinion.
However, it seems that you haven't grasped the reasons why some adults live, either through choice or not, in a different way to the one you deem appropriate.
I might deduce from this that you possibly prioritised becoming what you call a "competent adult" above other things, and therefore didn't develop, either by choice or by nature, a deeper understanding of other people.
Society has evolved so we aren't completely independent one from another. The fact that some people are in a position where they feel they have to know how to do "everything" is neither positive nor negative, rather a side effect of not having, or not wishing to have people they can rely on around them.
Are you saying that being completely self sufficient is the only way to live? Is the aim to always have money which can be exchanged for services the top tier, or is being independently competent in every single field more worthy?
Looking down on others, who for whatever reason live differently to you, and then accusing them of not adapting to the way of life you presume to be superior, is really tiresome.
Your "lifestyle" is of equal value to anyone else's, not more. If a woman wants to live as a 1950's housewife she is in no way less than you, or is she responsible for the "struggle" in society.
Individualism is not seen as the perfect way to live in many countries, but it's not about being right or wrong, it's about respecting other people's choices.
