This is something that I actually interesting culturally. Here in the US multi generational family homes are essentially considered a bad thing, but down in Costa Rica where my family is Multi generational homes are maybe not a goal per se, but something expected as your parents age, or as your kids grow up. You’ll grow up, move out for school, to get a job, and as you get older you’ll try to stick next to your family, and eventually your parents move back in so you can take care of them.

Obviously doing this out of necessity is bad, but a fun culture difference to observe.
