It really is an attitude. I am a fan of Zac Brown Band. They came to Atlantic City to play a concert. The tickets would have ran me about $1000/pair for mediocre seats. I can easily afford this, but seems outrageous to me, so no Zac Brown for me. This younger generation seems to have money for everything except important things (like college loans or saving for a home) and just like to say how much harder their life is and they are victims.
Wait, the "Younger Generation" is buying $500 a seat to see Zac Brown Band? This is absurd - Zac Brown Band is an old band. Even somehow expanding the pricing of one band for one concert in one location to "all concerts for all bands everywhere" (which is a huge leap), that still only proves that "enough" people will pay absurd prices for stuff. It says nothing about what generation is going to these concerts. Are you really going to argue that any generation, going back to at least 1900, didn't have a number of people who would spend absurd prices for something - and this is a new thing in the 2020s? And you're going to entirely ignore that if you adjust for inflation, college and houses were multiples cheaper than they are today in the 1950s-1970s?
Now, I'm not going to argue that there's sure a "victim olympics" going on, but it's certainly across all generations and communities as far as I can see. Hell, Trump spends a lot of time playing the victim, and he's the President! He's certainly not a "younger" generation, nor was his life hard, but he partakes just the same.
However, I also tend to agree with Pinker - that on average - life is better today than it was in the 90s, which was better than it was in the 70s etc back through many generations. It's not always the case, there are documented dark ages, but so far we're not in one quite yet. People like to act like "everyone" in the 60s could buy a house, that was far from the case. And much as we decry consumerism, I can't argue that having a smartphone and services like Walmart delivery make my life much better now than it was in the 90s. The Internet shopping in general has opened up so much choice and better options than back when us rural people had like 3 chains and you had to drive 45 minutes to get from the house to one, and the big cities were 1.5-5 hrs away one way.
Medical care is actually so much better when you can get it, and to be honest, I'm not sure it's not a wash between getting someone who can't do anything about your issue because there's no understanding how and struggling to get to the right person or get coverage for the treatment that exists. At least some people are getting treated, so on a societal basis I'd say that's a positive.
Bitching aside, I do think more people are able to travel (so far anyway), get better experiences, have fun in different ways and just enjoy life more. More people aren't doing backbreaking labor, and so live longer and better lives.
Price aside, college and education all around is more accessible than it ever was with more options. These all seem like good things to me. Anyway, I'm rambling - read up on Pinker if you want the long form "many many many things are better now".
