I currently live in a very red state with an anti abortion law that took affect the moment Roe was overturned. There are no exceptions and we even had our own case of a young girl being forced to give birth from a rape because her mother could not afford the hours long trip to the next closest abortion clinic. That young girl's life is forever hindered by giving birth too young; now multiply that by 1000s should a nation wide ban be placed. Or the radicals who want to remove no-fault divorce and keep abused women in dangerous relationships. I have the means to escape, but that's a very much a "fuck you, I got mine" mindset when I recognize the abject poverty that exists for the majority here.
We've already been through this 8 years ago after Hillary lost the election. Democrats didn't "wakeup" and over a million people died in the US from a botched pandemic response. Accelerationism is a privileged view when you have nothing to lose, but those less fortunate are hurt by its repercussions.
Our current system is broken and no means perfect, but burning it all down isn't how we change it. It is far more likely that an authoritarian takeover will occur instead of the rose-tinted glasses utopia that these non-voters think will happen. All the death, pain, and destruction won't magically shock people into changing it because they'll be too focused on just trying to survive the hellscape wrought on them.
Hillary won the democratic nomination because older voters turned out more to vote in her favor. While young voters primaries for Bernie, the overwhelming majority of those voting in the primaries were older.

If more youth turned out to vote in the Primaries in an equal or stronger force than older voters, Bernie would have had the nomination.
Regarding Democrats not doing anything to support immigrants, DREAM Act and DACA were ushered in with greater force and an expansion was attempted due to Obama despite Republicans consistently fighting it or Republican Governors suing against it. The expansion was stalled by our conservative Supreme Court, but would have been successful if we had more left leaning judges. General overview. It's not that democrats are not attempting these things, but more so we lack the majorities in Congress and on SCOTUS. There is the potential of more justices retiring in the next presidential cycle and whoever wins has the ability to make the court more right or left leaning which will have an impact on this.
