If you want people to fight inequality with you, you have to first prove to them it's actually a problem. It's a bit of a leap to convince somebody that just because Bill Gates is much richer than the typical person, somebody more deserving must have gone without for him to get so rich.
Japanese video game companies pay like 1/3rd or less what USA video game companies pay in salary. AFAIK similar things are true for other industries. Maybe not as bad as 1/3rd but that's not relevant to the point below.
In Japanese school (17 years ago) my teacher brought up the topic that CEOs don't get paid as much in Japan so it's more equal. My response at the time was "why do I care that my USA CEO makes 100x my salary and my Japanese CEO only 10x, the 100x CEO is still managing to pay me 2x to 3x more than the 10x CEO."
How true that is overall I have no idea. I can say that video game programmers in Japan with 15 years experience make less than interns at Google.
