Why do you have kids if you know you can't afford them?

As the son of parents that struggle financially I really don't understand the logic behind it,cause if you can barely take care of yourself why would you bring another human being into the equation,and then you turn around and blame me,the child for being too expensive when I never asked to be here,you had the choice of not having kids and not dealing with the financial obligations that come with them but you still chose to have them,like why do you guys do this?? If you're suffering why are you bringing more lives into that suffering,can't you see that you're setting them up for failure by not being financially stable parents?
