Not arguing that inequality is not an issue, it certainly is. But to say that only the wealthy have benefited distorts the picture. Rockefeller or Getty could have spent all their billions and never owned an iPhone, or had a child in vitro, or videoconference with a person in another continent, things taken for granted by everyday non-billionaires.

The average person's "wealth" -- as measured by life expectancy, access to vaccines, medicines, and advanced procedures, clean food, safe shelter, labor laws (in most countries) plus an enormous variety of entertainment and leisure options -- continues to increase over time, even if wealthy people get the majority of the gains.
