I'd recommend watching the Miliband interview with Evan Davies which was on BBC earlier.
Miliband is hardly a radical lefty, but he shows some genuine passion when he talks about inequality which is nice to see for a change, especially after 5 years of Cameron, Iain Duncan Smith, Osborne and the rest of their vile cronies who have assaulted low earners, the disabled, etc, at every opportunity.
Evan Davies played that clip from the last days of the thatcher govt where she was explaining the difference between herself and socialists by way of how the gap between rich and poor should be. Miliband shot it down and argued with some conviction that to have strong productivity in the country and a stable economy, workers need to feel valued and this is done by fairer redistribution of wealth, not just by making the rich richer.
