One of the problems of our economic system is that we can "sell" our bad things - wash our hands of responsibility and it be someone else's problem.
We can buy clothes made from slave labor, or sweatshop labor, and ... are we responsible? Did we have anything to do with it?
We can buy electronics containing tantalum, which funds the war in the Congo. Are we responsible? Did we have anything to do with the deaths of millions?
It seems like many people can be responsible for this. Eg, the council, for providing substandard housing. But afters of "austerity", they probably don't have the resources, so can we blame that austerity-mongers? Or go back to the Thatcher-era and the selling off of council housing?
Really, this isn't simple finger pointing, but the indictment of the system - "a 'shocking indictment' of inequality in the 21st century", to quote the article.
