My net wealth is massively negative and will remain so for decades... and yet any fair assessment of my quality of life is that it's great. I can't afford a car, but I can still be chauffeured around like a celebrity at the push of a button on my phone. I can summon almost anything I want from across the planet and have it show up in my doorstep in 2 days as if I was a king. I have access to probably 99+% of the knowledge, information, art, entertainment, and telecommunication tools of the richest guy in the world. I could hardly care less that some people are preposterously wealthy while I'm "poor", because I really think my life is probably at least 80% as good as theirs is. I also hope for greater equality in the hope that it would further spur creation and make people feel more comfortable with risk taking and self-fulfillment or self-expression. But, thinking that millennials/post-millenials/future generations have been somehow "screwed over" or have been given a world on fire is an ungrateful and borderline laughable delusion.
The "previous generations failed us" mentality implies that we are somehow due all of the good things previous generations have given us (even though the only thing most of us have done to "deserve" them is exist) without having to deal with any of the bad. I think if some people had their way, we'd be shivering out in the cold and bartering mounds of dirt for big circular rocks because they'd have villified the people that first cut down a tree for shelter or crucified the people who thought that steam engines were an innovation.
