The difference between the two vastly different subjects going on in this thread is amazingly entertaining

The population is getting filled at a vastly higher rate by the lower class. The lower class typically contributes far less than they consume and depend largely upon government assistance for subsistence/survival. The children of the lower class have plentiful opportunities to help them succeed and elevate themselves out of the vicious cycle but usually fail due to the cultural issues brought on by their socio-economic status. I f we continue to allow our society to be flooded by these types of people, we allow the system to completely crash.
My wife and I both have college degrees and successful careers, we pay a shitload of taxes and are actively involved in our community. We have two kids, both if which are honor students, successful in sports and are actively involved in several extra-curricular organizations. They will both graduate from college and have professional careers. I mention this because we knew the limits of our resources and purposefully stopped having children (snip, snip) before we exceeded our capacity to support. Even in our most trying times financially, we have never needed to use government aid to support our family.
There should be limits to how many children a person can have, relative to that person's ability to financially support them. No sensible reason exists for an unemployed single mother of 8 (from 5+ fathers) or 6th generation welfare families.
