That the rich get richer faster and hoard more and more wealth while others fine their wealth decreasing over time is inequality.
> And it's not necessarily a problem, because even the super rich can't spend all of what they earn, and that money ends up being recycled in the economy (investment, etc..).
This is the trickle down theory, which is not true in any way whatsoever. Wealth does not get reinvested or redistributed in a way that reduces wealth disparity.
> It's rather about: is everyone getting richer ? And the answer is clearly yes.
This is demonstrably false. Don't confuse the availability of consumer goods with wealth. In the US, for example, actual wealth for low and middle class people/families has been declining for the last 30 years or so.
> Even the poorer people are getting a bit more than before and can afford a better life than their parents.
This is not true either. Homelessness, poverty, and unemployment rates are measured and we know that there is no long term downward trend for these things even as wealth disparity gets worse.
> That's what abundance mean: it's not about who gets the biggest share of the cake, it's the fact that cake is growing and everyone gets more cake than before.
Tell that to the people that are homeless or go hungry every day.
