We might hope that the law as a profession does not vanish, because justice may vanish with it - but we could probably do with far fewer lawyers. Since I think agriculture will come back closer to the center of life, I think there will be many vocational opportunities there - especially with the so-called 'value-added' activities associated with food production. That's a windy way to say more local wine and cheese-makers - and probably fewer giant factories producing cheez doodles and Pepsi Cola.
