What is wrong with Wealth Inequality?

This was a question posed to me recently, this was my response.

It's a theme which runs on for some time in the Spirit of Laws, by Montesquieu.

It's totally inappropriate for a direct democracy, he says, and needs to be kept in check in an electoral democracy.

In what Manner the Laws should relate to the Principle of Government in an [Electoral Republic]. When Montesquieu mentions a "popular government" he is referring to a direct democracy.

The above link is Montesquieu is arguing that wealth inequality undermines virtue.
