Inter-generation living has always been part of african culture. If you have enough living space it works well. You have the grand-parents taking care of the little ones, the working age guys go out and hustle and bring money, the unemployed take care of household chores. So long everyone is pulling their weight you will increase family wealth. I also tried moving out early but my dad told me to stay put and use the rent money to build my sacco savings. It's best thing my folks did.

In the first world you move out early and when your parents are very old just throw them in the old peoples home. The western culture of individual living is not the ideal thing to copy.
