Children are good for society, fiscally and in every other way. Children who are well-cared for, who aren’t forced to go to school sick or spend lots of time alone, and parents who aren’t utterly exhausted and wracked with guilt at all times, make families who give stability and peace to society as a whole. So even if we’re only looking out for our own self-interest, it’s best for everyone when parents are given as much freedom and flexibility as possible to devote to their children. Children are not a hobby or a side interest: they are life itself. It only makes sense for employers to take that into account.
