Robin Hood took from the rich to give to the poor. Fixing inequality within the local surrounds of Nottinghamshire was clearly achievable. All it took was a straightforward system of mandatory redistribution enforced by a band of merry men. But today it is often said that foreign aid programmes take from the poor in rich countries, to give to the rich in poor countries. Inequality between countries is therefore a complex thing to fix. Poor people in poor countries are increasingly better off as they close the global inequality gap, but poor people in rich countries (so, not poor poor in a global sense but poor by rich-country standards) are falling further behind their wealthy neighbours in the local inequality stakes.

​There are many branches of liberal thought, and much disagreement on how to classify the different liberal perspectives. One way to distinguish between them is by the importance they attach to private property.

There are two kinds of equality – formal equality and substantive equality. The idea that all men are born equal expresses formal equality, and everybody agrees with that. No problems there. But the idea that everybody should have the same amount of wealth expresses substantive equality, and not everybody agrees with that. Why should people be equal in relation to the amount of stuff they have? Why is it unfair for someone else to have more stuff than you?

 
Many people today assume that life is ideally supposed to be fair, so they take it as self-evident that others must be forced by law to provide various things from within their own resources, in order to make everything fair. In other words, everyone has to share nicely with those around them even if they don't want to. In the pursuit of fairness, other values such as liberty and the freedom to choose are relegated to the sidelines. This results from measuring the value of how much you've achieved by reference to what others have achieved.

​There are many reasons why foreign aid and handouts do not succeed in lifting anybody out of poverty, but one of the main reasons is that progress requires effort. Sadly, there is no effort involved in being the recipient of a handout.

Justice and equality are excellent ideals to aspire to; since these ideals are offered as the reason why we pay taxes - to collect mandatory tax donations from the rich and use that money to provide resources for the poor so that it's just and equal - nobody can credibly disagree with the need for taxes in a civilised society. The only trouble is, nobody really questions what is really meant by the concepts of Justice and Equality in this context.
