It's made from foods that were gathered by hand from the wild. Long
enough ago such foods cost only labor and what the poor had in abundance
was labor hours.

As labor became more expensive over the decades and as wild foods became
more rare, the name gradually switched from an observation of current
status to an obscure historical reference to the days of low population
densities.
