Been watching this show for years, and the conclusion is inescapable:
These people should not be having children! Or at least no more than one or two.
Am I being too harsh? Maybe, but it's like a broken record on this show: the parents have a couple of kids, then screw things up by having MORE! Their already flawed parenting abilities are stretched to the breaking point and then the extra kids send the situation into dysfunctional territory. And it's not just this show; it happens everywhere. My wife's a schoolteacher and it's just mindboggling how many young, poor, ill-equipped people have four or more kids. It hurts the kids and burdens society at large.
Birth control! Live it! Love it! USE IT!
