I don't think poor people think of their finances when they have yet another child. In fact, they just accept what it's happening as being absolutely natural and even if they don't have sufficient food to put on the table, they don't care because somehow they will manage it by getting another state allowance or going out to beg (I know this sound terrible, but where I am from, it's a common practice). All in all, the less educated you are, the less worries you've got. Only people with education are obsessed by the future and try to be prepared for everything especially fo bringing another life in this world.
