Go multiply doesn't also mean people should start producing children without having an income or a job at hand. Go and multiply is only used for those who are prepared to go into marriage, and being prepared for marriage doesn't guarantee one must give birth to many children but only the ones that you can cater for. When it comes to child bearing, you need to be very sensitive that no one is coming to help you, which only you have the responsibility to provide for the children.
You know some persons are funny to the extent that they fail to understand that what makes you a complete parents is the ability to provide for the family, whats the need of multiplying problems for yourself when you can't solve the problems, kids are gift from God we know that but it becomes inadequate decision to have many kid when cant be able to take good care of them, the holy book saying go into the world and multiply, is there a anywhere it says, go into the world and multiply without being able to take care of the offsprings, people are just good at saying things that was said but at the same time being unable to get the full knowledge and information such saying carries.
It becomes a big problem to a man that didn't plan well on how many kids his income can carter for till they grow up. Those are the important things that a responsible man should put into consideration before giving birth to the number of kids he want. When you give birth to more than the number of children that your financial strength can contain, you have brought more problem to the society because the society will also suffer for it.
