>> Tech entrepreneurs and investors hold the power to change the world faster than anyone else. More wealth inequality --> closer to the dystopia. It rational for anyone with power to influence the world and possible future to contribute to the decrease of wealth inequality.

Unless they think that their lives will be better by increasing inequality, particularly in their individual case (cf. Tragedy of the Commons). And that may well be true, as they would disproportionately hold power and capital. Is it better to be a rich man in a society slowly going to hell or a poor one in a society slowly on the rise?

It's a non-empathic viewpoint, but I can understand why some would consider it rational and self-interested.

Wealth hoarding is mostly a hyperprophied survival instinct. The rational person would optimize for happiness, not wealth. The connection between those is not linear, see: http://blogs.wsj.com/wealth/2010/09/07/the-perfect-salary-fo...

Also helping other is a significant factor in emotional wellbeing.

I mostly blame the current snapshot of evolving social system, not the actors, even psychopathic ones.
