Such successful economic activity can be accompanied by things like the Pupil Premium (targeting funds at the schools attended by the children from the poorest homes), increased spending on the NHS and a cut in the taxes of the lowest-paid (the last of which Bob did acknowledge in his question). As Nick Clegg said in a speech today that I genuinely think was very good (I know people are cynical when grassroots party members say things like that about speeches by the party leader, but I really believe that this is a particularly good speech and well worth a read):
As a liberal party, we are unique in being equally committed to a dynamic economy and a fair society.
We know that only a successful economy can create the jobs and opportunities for real fairness.
But we also know that free economies do not magically produce fair societies. The Government has a moral responsibility to create the conditions for real fairness – real opportunities for ordinary people.
