I find it strange that people keep making kids even when they cannot support them. In the impoversed countries we have tens of millions of people added every year. The western countries can only help to a certain point. Eventually these increases will lead to catastrophe that no one is going to be able to stop.
Good answer, it's advisable not to have a wife or child if you can't afford the full responsibilities in the modern world e.d. good food, education, health, cloths, and shelter e.t.c. because without taking care of your child then they'll become the victim of the current world abuse... Like drug trafficking or the worst terrorism!
