> Since the 60's? Perhaps. Since the rest of history? No.
The thing he's experiencing which makes him say that we are growing more and more unfair, that's exactly what you're experiencing when you say that we've grown more unfair than 60's.
But let's really see how things are today, in the 60s, there was no Internet, so majority of the opinions were dominated by what was in the mass media, so that served as a Schelling point of opinions. Today because of free exchange of ideas on the Internet, people are just holding more precise and wider set of opinions.
Back in the day for a conservative to say that we should shut down the Dept of Education, would have met by resistance by most people around them and this opinion would be shut down. But now, you can just find people who believe exactly like you on the Internet. You can find a blogger who would talk about how eliminating DoE would work, and nurture this idea in your head, and once you have enough people, you can get politicians (who are playing a game of prisoner's dilemma) who are willing to represent your opinion in order to get an edge on their opponent.
Similarly, it would and should be unimaginable and unfeasible for someone in the 60s to hold an opinion like an average Tumblr SJW holds, but today it's perfectly feasible. But is society really more unfair than 1960s? What about 1980s? What about 1990s? When you look from the perspective of minorities, it clearly isn't.
However, a lot of young people have economic conditions in mind (which people on the left describe as 'rising economic inequality' and people on the right describe as "America losing it's place in the world"), but both these things are essentially the effect of increased globalization, observed differently, which has resulted in immense amount of prosperity for the poor people in the rest of the world. Now since the gates are open, an average American has to compete with a Chinese worker or an Indian software engineer, the true place of an American is being realized. Being the largest business in America is definitely worse than being the largest business in the world. If Facebook wasn't able to operate all over the world, then clearly Zuckerberg would be less richer than now.
But at the end of the day, the world is moving towards a more fair place. Is China more fair now? Yes, but if you believe that the role of Chinese party is to facilitate the arrival of Communism via maintenance of Socialism then you would obviously think that China is growing more unfair.
