Well, lets buy a house, car.. wife should stay at home for couple of years, education, health care...
That’s awfully presumptuous and gendered.
>buy a car
Assuming you don’t already have one and live somewhere where a car is needed. Plenty of parents with no cars or who had 1 and continue to live with 1.
>buy a house
Plenty of people do that with or without kids and plenty of parents rent.
>education
Plenty of people go to public school.
>healthcare
Valid but also people’s situations vary wildly here.
