Fair inequality

Of course it is not faire to live in inequality. But the easiest way to make everybody equal is make make everbody as poor as the poorest. But who would you help with this action?
Probably nobody.
I think Inequality is usal. It is not nice that there are people who need to hope that they can eat enough to survive but therefore is a society made. To help the poor and weak. And that should be fairness, that the rich people help the poor.
