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
So perhaps they enslave the most intelligent and able bodied males
And give more and more money to ghetto culture men & single mothers
This multiplies the least productive of people which would result in a economic collapse if it were not for improved technology
The improved technology allowed the enslaved employed men to be more productive and also to build new productivity increasing technology
The percent of intelligent and able bodied men decreases every year without economic collapse
