Assuming freedom to choose, I would say policies should still try to steer choice to address social needs. For example, let's say there is an imbalance in F:M physician ratio such that one class of people are being underserved. Or the market isn't producing enough physicists, for example, then step in and add artificial incentives to attract a different population.

Note, I'm not insisting on equality of outcomes, because to me that's really not the general objective, given a population can have individuals predisposed for different things. For example, in farming communities we don't expect to see the same interest in urban planning as in cities.
