Fairness runs in the blood of the Labour Party and the British people.
It is part of who we are as a country.
That is why figures out today should make David Cameron and his government hang their heads in shame.
The Department of Work and Pensions will publish statistics - delayed from before the last election - showing the first rise in child poverty for 10 years.
They are expected to show there are 2.5 million children living in poverty in one of the richest countries in the world, our country.
The number is expected to rise to five million by 2020.
These are the kids in Britain who go hungry and cold.
These are the kids who don’t have one week’s holiday by the sea or the latest phones like their friends.
They have poorer health, worse qualifications and poorer prospects than those they sit next to at school.
And David Cameron’s answer: not to tackle the problem but to change the definition of child poverty. Doesn't that just sum this Prime Minister up?
We learnt yesterday that the Cabinet did not spend this week’s meeting discussing how to improve the life chances of these youngsters, but making sure some of them did not get counted in the official numbers.
It is fiddling the figures.
It does nothing to solve the problem.
And, as the Child Poverty Action Group has said, when the numbers are flashing red, you sort out what is wrong, rather than turning off the warning light.
If I am elected in September, I promise that these children will not be forgotten children over the next five years.
I say that because I remember from my own school days the lads in the PE changing room who had to wear their sister's hand-me-downs. Those memories never leave you.
My own background will make me the Prime Minister who turns the tide on this scandal. It gives me a very different take on these things from this Prime Minister.
I have not said there can be no cuts; we do have to bring the deficit down. There has to be a credible plan. But the Burnham plan won't punish the poorest in society.
We know there are £12 billion worth of welfare cuts still coming down the line.
It is a disgrace we don’t know where they are coming from.
If George Osborne had wanted a mandate for cutting tax credits and disability benefits and pushing child poverty up, he should have sought it at the election.
Instead he kept his plans hidden and now after the election intends to hide the consequences of them.
This is not the grand long-term plan they claimed but a grubby short-term plot.
There are mum and dads who rely on their child tax credits and their child benefit who are worried about how long they will continue.
There are disabled and vulnerable people who are frightened they will lose benefits they cannot replace.
I tell George Osborne this today: he has the fight of his life on his hands if I become Labour leader.
I will always stand up for people with the odds stacked against them.
A Labour Party I lead would offer a better solution.
We need to look at the idea of tax incentives for companies paying the living wage - the best welfare policy is a decent wage.
We need to fix a broken housing market and unleash the biggest house building programme in a generation - investing in bricks and building is the way to bring down reliance on housing benefit.
That is the Labour way of doing things.
It is better for the country because it will save the taxpayer money.
It is better for those kids who will have more chance of being healthy, getting good qualifications and decent jobs.
It is part of what I mean when I say Labour will be the Party that helps everyone get on in life.
The hopes of people at all levels of society are pretty much the same: a secure job; a decent home; a good standard of living; prospects for their kids; and proper care for their parents.
But the reality is that, for far too many people, these dreams are dying.
Labour's modern mission must be to revive them.
Tackling child poverty is part of my mission.
We still live in a country where the postcode of the bed you are born in pretty much determines where you end up life. I came into politics to change that - and I am ready to put my plan into action.
