I do use them, but I have an academic background and stable job with a permanent contract and good income. To make or to net make the decision of having children often comes from a very privileged position. However, the poor educated people with low ecosocionomic background are the ones who often become parent when they are very young adults or even youths. They are the ones that can't make this decision and have to suffer throughout their lifes with shitty jobs and shitty pay. If from such a position you try to create a better future for your children, you do need to make the grind.
