It wasn't but you had the opposite of the effect that you have now. Right now the top 1% are getting a lot of the additional wealth that's being created, while the bottom 99% stay mostly the same, or improve at slower speeds. So yes, this means that we are headed towards a more inequal world, even though the situation improves for everyone.

Turn that now around, and kill a lot of people from the bottom 90% while letting the top 10% survive at higher rates. Suddenly, the world looks way more fair, even though the people at the bottom still have nothing.
