How economic inequality harms societies | Richard Wilkinson

You seem to be talking about average wealth and social mobility. This is different from inequality, which is about the distance from the bottom to the top. Some of these results are counter intuitive. For example: There's data to show that the top quartile of earners in low inequality countries live longer than their top quartile counterparts in high inequality countries, even if the high inequality counterparts earn much more both in absolute and relative terms. Edit: Since this is getting downvoted, here's a talk that spends 17 minutes listing studies showing that this is in fact about inequality, not average income. [this video]

- Secondly, assuming that the "inequality gap" is necessarily a bad thing, which I don't think anyone has shown Actually they have.

Yes, it is a bad thing in almost all recorded metrics. - First of all, doesn't anyone see the correlation between increased government power (revenue/spending) Nope. I think revenue spending isn't really good metric of government power and so far no one has proved that. You are free to test your hypothesis though. I'd wager that there is quite a bit of income inequality if your gov. revenue is low but they spend a lot of money.
