I'm sick of everyone shaming the guy for having 4 kids. It's not like he can reverse time and stop them from being born. So saying he can't afford kids only serves the purpose of making the guy feel bad. Besides, you don't know enough about his situation to criticize his decision to have children.
He should have not had any kids until he was stable enough, let alone four. With his previous job at a factory too?
Not. Smart.
