Much as it will irritae the predominantly Tory Ab membership, I'm afraid it all started with "There's no such thing as Society" from Margaret Thatcher. That combined with her rampant Yuppy me-me-me followers set the rot going, and no Government since has made any effort to change it.
This attitude brought the country to its knees in 2008, but still we didn't learn. 9 years of Austerity with the rich screwing the poor and decimating the Welfare State didn't help, because this "I'm all right Jack" attitude now permeates further throughout the population - Greed rules OK.
Left Wing politics is often labelled as the politics of Envy, but Right Wing politics of Greed becomes de rigeur.
