These people shouldn't be criticized, they should be applauded for not having children. It is much better that they stated their true feelings on the topic, rather than adhering to societal pressures and having kids anyway. If these were inner-city, low-income people being interviewed for the article, we would say how brave they are for breaking the cycle of welfare dependence.
I know of young couples (with children) who aren't mature enough to properly take care of themselves, much less their offspring. These kids arrived due (in part) to relentless pressure from their parents. Too bad they couldn't just say, "No!"

Innercity low or no income people seldom seem to have the urge to go out and have no children.
