He called for businesses to act more responsibly in what he called "a more ethical capitalism" where business is not just about making money.
Here are the key excerpts of what he had to say, as reported by the Press Association:
"We need a more ethical capitalism. I don't think the answer to the current crisis is to tear up the market system and go back to 1970s-style socialism, but we do need a more ethical capitalism in which we recognise that business has real responsibilities. Business is not just about making money. It is also about acting in an ethical way and I think we need to build a more ethical capitalism in Britain as we come out of this dreadful recession."
He reiterated his commitment to the environment and quality of life issues in these tough times:
"As we build our economy for the future, I hope that we can build into that economy a better balance and we make sure that quality of life issues do matter. I think that's one of the things we have got to learn from the last few years. I think it would be a crying shame if because economic times are tough we threw the issue of the environment out of the window."
Meanwhile, he also stood by his commitment to support marriage:
"We need to do more to help families and support marriage and commitment and make sure that everyone builds a society where we are responsible for the children we have and for bringing them up. That is a social policy, but it has also got huge impacts on our economy. If we don't help couples stay together, if we don't build strong families, then what we get is family breakdown, which has huge costs."
He repeated his call for a loan guarantee scheme:
"The real problem is that the banks aren't lending. In order to to stop this credit crunch destroying tens of thousands of good small businesses, the government needs to act to ensure lending. Otherwise, the people paying the consequences for Labour's debt crisis will be very good small, medium and often large businesses, which are doing OK – they may be having a difficult time and laying people off but they shouldn't be going bust. They are going bust because the banks won't lend."
And Tory leader concluded:
"This is Labour's debt crisis, yet their solution seems to be even more debt. What we will be arguing for in the new year is to try to make sure we can build a more balanced economy. We need to encourage saving, rather than just borrowing. We need a greener economy, a more balanced economy, more manufacturing and not just services."
It is his call for a "more ethical capitalism" which will attract the most attention. Margaret Thatcher's oft-misquoted statement that there was "no such thing as society" was endlessly used by political opponents to caricature Conservatism and capitalism as heartless and uncaring (even though the words were always taken out of context).
David Cameron - very much on the advice of Steve Hilton, I would imagine - is clearly trying to establish himself as a "Caring Capitalist".
Update: As has been pointed out in the comments below, Mr Cameron also made a scathing attack on Gordon Brown's VAT cut.
