It appears that the Romans, after getting the Brittons to rebuild the city they had torched, used the bones of those Brittons as the foundations for their new defensive fort. Clearly they saw the poor as 'sub human'.
Co-incedently our current government want to punish those who burned parts of the city to the ground by having them do compulsory community work, and as a pre-emptive strike against others to get all poor people to rebuild the damage and do all those erksome tasks people refuse to do even if you offer them the minimum wage. Will our rulers go as far as to use the poor as foundations as their predecessors did?
I think not because our current leaders are more sophisticated than the Romans. The Romans slaughtered the 'cattle' and then had to get others to do the work. The Tories are happy to milk the poor within an inch of their lives and so perpetuate their servitude for maximum profit. 2 thousand years of progress to feel proud about.
