Everton and Anfield are two of the most impoverished boroughs in Liverpool. In fact, nearly all of the north end of Liverpool, from Bootle through Vauxhall, Kirkdale and all the way to Kensington is largely impoverished, lacking investment, and does suffer from what you describe, on a large scale. The development of the new stadium, and the area around the Titanic Hotel and the Tobacco warehouse, takes the city centre developments into the north of the city, and will, likely, be plagued with those issues. The development of this stadium could make a genuine difference and I hope that Everton's issues are short-lived and fully resolvable.
I remember visiting Palermo and speaking to a bar owner. He described how investment in the city was pretty close to zero, and had been for decades, because there was no profit in development - the protection money demanded by mafia simply ate into the desire to develop, and Palermo remains a city MUCH in need of it.
