Re: I do not think it means what you think it means...
Wealth inequality is a nonsense. I'm one of the poorest people on the planet according to my wealth, but in actuality I have extremely high levels of comfort to go along with my high net debt. This makes my wealth less than a subsistence farmer, who at least owns his land outright and has positive wealth.
It is a nonsense pushed out to make for interesting headlines. The fastest way to reduce wealth inequality would be to forbid people to take out mortgages. This doesn't make their lives better, is worse in the long run, it just moves people from negative wealth and good long term prospects to positive wealth and no long term prospects.
That is clearly nonsense, it just demonstrates what an intrinsically bad metric "wealth" is to measure the inequalities that exist in society.
