In the New World

Persons that will become invaluable if we have some kind of ecological/economic disaster:

blacksmiths, chandlers, weavers, farmers, potters, sailors, herbalists, medics, tailors, millers, cobblers, knackermen, woodspersons, midwives, joiners, spinners, builders, and others that didn't occur to me in my sleep.

Persons who will become less valuable if we have some kind of ecological/economic disaster:

financiers, CEOs, politicians, accountants, HR, administrators, idlers, insurance salepersons, luxury manufacturers, and others that didn't occur to me in my sleep.

Persons who are not valued now, and won't be valued then, but should be valued in both cases:

musicians, story-tellers, artists, truth-speakers, dancers, teachers, reporters, poets, mentoring persons, and others that didn't occur to me in my sleep.
