Let’s not delude ourselves. Being in single parent household doesn’t condemn a child to failure but having both mum And dad there is a much better head start to have.
Of course there are exceptions if one of the parents isn’t fit for purpose but most of the time, that comes out of poor decision making.
You can can’t get knocked up by a wasteman and expect him to change once a baby arrives.
Also, the village mentality is gone. How many of us really know our neighbours? Did my parents know every single thing I was doing? Of course not, but I was shook to act a fool on the road in case a family friend or relative saw me. That has changed with this generation. The previous generation has really failed us.
