This really gets me.
We as a society do not need more children. Popping out a baby is not an accomplishment. Hell, most babies these days are accidents. It seems strange to me that someone would choose to do something that a lot of people do accidentally, and then expect some sort of recognition for their supposed sacrifice.
We as a society simply don't need more babies. The "sacrifice" is unnecessary at best, and possibly egotistical at worst.
New generations innovate, and they take care of the aging.
Having kids is actually a huge sacrifice on the part of the parents that ultimate benefits society as a whole.
