There's no necessary connection between maximizing social utility or economic wealth and creating a flourishing democracy. The first does not guarantee the second. The only way to create a flourishing democracy is to find ways to reason together about the big questions, including hard questions about justice and the common good, to reason together about these questions so that we as citizens can decide how to shape the forces that govern our lives.

The way things are does not determine the way they ought to be

I would include non-medical sex selection as one of those practices that I think is morally questionable and that can carry adverse social consequences.

Parenthood is a school for humility. We can't choose the precise traits of our children, and that is morally important. It teaches us what William May, a theologian whom I greatly admire, calls "an openness to the unbidden."

Parental love is not contingent on the talents and attributes the child happens to have. We choose our friends and spouses at least partly on the basis of qualities we find attractive. But we do not choose our children. Their qualities are unpredictable, and even the most conscientious parents cannot be held wholly responsible for the kind of child they have. That is why parenthood, more than other human relationships, teaches what the theologian William F. May calls an “openness to the unbidden.

In some parts of the world, that sex selection for boys - and it's usually for boys - reflects sex discrimination against girls, and it leads to very large imbalances - in China, in Korea, in India - in the population between boys and girls, a vast disproportion of boys to girls, and it reflects really this discriminatory attitude toward girls.

They say the state should not impose on its citizens a preferred way of life, but should leave them as free as possible to choose their own values and ends, consistent with a similar liberty for others.
