the bulk of any primal surplus population
is of course
up rooted wanna be subsisters
( culled from all forms of peasants from yeoman thru tenant share cropper to peon bondsman slave and tribal cultivator herdsman hunter fisherman )
and to a lesser extent
traditional artisans
back pack traders and
any other socially useless anachronistic "retainers "
these millions once cut "free " of the land with the disintegration
of traditional modes of product and exchange
become in time
the source of industrializations prolery
that is if they cCAN be absorbed
by market based local wages systems
if not ??
they turn outlaw ....but all too infrequently
rather more commonly
they drift urbanward
where they are drafted into various forms of the great and venerable
army of mass misery of getting by somehow
nimbling at the margins of "emerging cities"
with the occasional
famines
pandemics
civil wars
genocides
gulags etc etc etc
out lets ???
migrations
mostly unauthorized mass migrations
ie
they morph into
the utterly unwelcome easily exploited
undoc millions
producing and serving away
in the advanced world
