Every year as technology improves either
the average number of working hours per employed male could decrease
or the percent of the population that is unemployed could increase & the number of working hours per employed male could stay the same
let's presume it is the 2nd & not the 1st
perhaps the economy will not collapse because although less & less people work more and more goods & services are produced per employed male
this might prevent overthrowing the system & so prolong suffering
As long as there is no economic collapse the ghetto culture men want to preserve the system and the able bodied and intelligent men will have more and more difficulty to defend them self against slavery because they are a smaller and smaller percent of the population
