At what age do you think it is socially acceptable for parents to not support their children financially anymore and why?
It depends on the childrens’ goals and the family situation. If the children are studying after school, they might need help from their parents for a while and it’s ok.
I believe it depends on the relationship between parents and their children.
20-22. Because at this age you should be able at least to earn money and cover your expenses. Especially after graduating from university when you can find a full-time job.
I have no opinion
probably when they are no longer students and can work full time
I believe that age doesn't matter and it depends on the situation and the relationship
