I hope you are correct about your generation's will to fight. As a millennial, I actually like zoomies and alphas (and a lot of Gen X). However, I think Boomers suck so much that they're the only real reason that "generation" discourse even exists. (That, and if you want to get technical, they are the only generation with an actual event tying them all together, the "Baby boom" post-WW2).
The core frustration of millennial existence is growing up with hope for a better tomorrow, and seeing it destroyed at a young age. Z and A never had hope in the first place, beyond the horseshit sold to them by influencers. And yet they go on. It's not like they have much of a choice, but I still respect it.
Politically or practically speaking however, I don't think we should lionize "the grindset" or whatever you want to call it. Drive is good, but everybody shouldn't have to be struggling constantly. That's the issue with the American conception of politics - both parties already agree that GDP is more important than anything else, and that naturally leads to the ongoing downward trend in standard of living and life expectancy we're seeing over the decades. When we allow our leaders to arrange society and prioritize like this, it naturally leads to a world where you must fight to survive, which is great for the dwindling contingent of people willing to live like that (and the ultra-wealthy), and horrible for everybody else. Worker productivity has only gone up regardless of generation, yet real wages keep going down. Neither the Democrats nor the Republicans care to address this; they're two sides of the same capitalist coin.
We're all going to have to do the work of reclaiming the government/political parties/mega corporations and turning them into something better for everyone. Just working harder isn't going to solve that. If it were that easy, we'd already be there.
