Cooking legumineuse notoriously take a long time and you very often need to soak them before hand.
Even the simpler stuff like lentils have at least twice the cooking time of regular pasta (20-30 min at least) unless you like eating stuff hard as rocks.
On top of that; it isn't very good as is and need quite a lot of skill to taste great. The usual way to make it taste good, is to use animal fats/meats and various vegetables broths/sauces. It's a very time consuming process and very often quite expensive as well because the raw ingredients are not necessarily cheap.
So basically what happens is that either you are poor enough that one person in the household is basically dedicated to this task (especially if it's a large family) or both are working, most likely middle class, and then there is very little time to do that sort of cooking without completely destroying the possibility of having a life.
