There are degrees to things, and wealth inequality in the US is the worst it's been since right before the Great Depression. The idea that wealth inequality on this level is 'no big deal' is as stupid as it gets.
I get that inequality has gotten worse, but has it put us in a unstable situation? Has society collapsed? Are the roads destroyed? Is average lifespan now 0?
We have more billionaires, but we also have 22 million more people with health care due to Obamacare now.
What metrics are you using, and why are those metrics more important than other metrics people might use.
Until you can clearly define that, we might as well say the anti-globalists are trying to turn everyone into ordinary chunks of common matter.
