That's not the point they made. They pointed out that Gen X isn't in it, which is appropriate, being the silent generation. They were punk rock as kids, but reformed the moment they had to and didn't try to make any sort of change as a whole.
Gen X had it's Part in Memes and grew up. Like tech savvy boomers, Generation X seems predominantly stuck in the middle tier of the career ladder, overshadowed by their Boomer parents. However, they maintain a benevolent and generous attitude toward younger generations. They are fully aware that they will likely never own property, and having children is a significant risk. This painful realization hit them some time ago, hence their sense of empathy. The later you're born, the more pain you inherit.
You realise Gen Xers are all in the 40-65 age bracket now, right? Nearly all way beyond the deciding-on-children age. And heaps of them own property (at least where I live).
We will age and die in our office chairs, and our Zalpha children will burn our bodies to fuel their air conditioners. We will finally find our purpose. Don't worry about us: we are content enough.
