The feeling against the fat cats and the market is not confined to the issue of rail safety. Millions know that the government's plans to privatise London's tube system and air traffic control threaten still more disasters. On a global scale it is the bankers' thirst for profits which means the debt burden on the Third World kills on a daily basis. The pursuit of profit is the central logic of capitalism. The Paddington rail disaster has sharpened the questioning of that logic amongst millions of people.
Socialists have an alternative to New Labour - one that can answer the questions asked by millions.
The alternative lies in fighting for a rationally planned society controlled by ordinary people where need comes before profit. Our task now is to get that message across and do everything we can to build an alternative to Blair, Mandelson and the capitalist system they cheer.
