What, if anything, can be done to reduce the extreme economic inequality in countries such as the UK and the USA, which has vastly increased in recent years, especially as times have got worse, is a separate question. What seems pretty clear is that this inequality contributes to make life far worse for us in all kinds of ways, and it is healthy that we should recognise this.

Evidently there are limits on how far collective action by society can reverse this tendency towards increasing inequality. There are very possibly limits on how far it should be carried for that matter. However that is no reason to assume that nothing can be done and that nothing should be done.

The very least that should happen is that progressive taxation should be recognised as good for society, and that claims to the reverse should be recognised as pernicious nonsense.
