Wait... you are seriously blaming her for wanting a better future for FIFTEEN children she must raise alone?
She doesn't want a better future for her kids, she wants a better future for herself and she's using the children to piggyback her to a lifestyle of no work. No one has 15 kids because they love to have children when they can barely care for themselves. In her economic standing, she has 15 kids because it gives her checks in the mail to live off of without doing anything, and she gets sympathy relief from other good natured people.
If she wants the best future she can get for her kids, she'd get them the hell away from herself, because she has nothing worthwhile to teach them to have a better life.
