there is ZERO evidence on that! we have plenty of evidence of the opposite - you can immediately go and live in a country with equality and no billionaires - Cuba, for example, but no - you prefer to stay in the USA and downvote me - who lived through the socialism and saw what absolute HELL is when people like you are in charge.
I'm not sure what the GP's post was, but I'm genuinely curious. I have no experience of socialist countries, but I have several friends and colleagues who have emigrated over the last decade or so.
1. Is income equality the primary driver of a country descending into social turmoil?
2. If not, is the USA so politically and socially similar to those countries in other ways that an income equality system - or a system that moves in that direction - would be the proverbial straw that breaks the camel's back?
I'm particularly interested in #2 as a non-American.
Even though we have plenty of evidence and research that it makes society better for everyone.
And there is zero evidence that the more billionaires a country has the better it is.
