Apparently, yob culture affects 1 in 5 businesses in the UK, and costs on average £20,000 per company affected.  And they expect the cost to rise as the economic situation continues.

Mostly it’s broken windows and doors, and graffiti, but also petty theft and intimidation.
So I was wondering, would there be a point where there were so many young people out of work that the yob-damage overtook the economic benefits of businesses, and everything collapsed in an ever decreasing spiral of despair?  It might be interesting to do a story from the point of view of one of the yobs, who doesn’t think anything of the broken window that was actually the straw that broke the camel’s back and caused the collapse of western civilisation.

How would it feel to be that person?  Would they ever find out that they were responsible?
