It is the social and economic circumstances of what may be described as an underclass which has created a "predisposition towards violent protest". This is a sentence paraphrased from the following BBC News Report entitled "England riots: The return of the underclass" by Mark Easton makes this point:  http://www.bbc.co.uk/news/uk-14488486

It brings to my mind Mozaz's blog, Underclassrising.net.

Mozaz passed away in January this year. The following is taken from an article he published in August 2010 (article entitled "The More Things Change…"):

"What could interrupt our obedience? Contemporary insurrectionists are attempting to ask this same question now, though the answers many of them offer are equally limited. By themselves, neither voluntary unemployment nor gratuitous vandalism seem to be capable of jerking society into a revolutionary situation. Despite everything, we stand by our initial hunch that it will take a new way of living to bring about such a situation; it’s not just a matter of putting in enough hours at the same old tasks. The essential fabric of our society—the curtain that stands between us and another world—is above all the good behavior of exploited and excluded alike."
