It seems to me that the left often relies on relatively inexperienced and impassioned youth, and the critically uneducated (abject poor) to further their cause... which seems to have always generally been to ensure and maintain a ~1% in America. This of course is instituted by the ultra-wealthy in the United States, who are generally supportive of anything that keeps them in power and eliminates competition to their status.
With the exception of Bill Clinton in the 90s (to which we can largely place a lot of credit on the Contract w/ America), most Democrats have consistently overseen a decrease in the middle class, a shrinking of the lower "wealthy" class, and an increase in minority poverty. Every single time. When Republicans tend to come in, like Reagan, Trump, and even George W. Bush, there's always an increase in the middle class, and a gradual shift of the upper poor into the middle class, and the upper middle class in to the lower wealthy category.
The Democrats tend to implement policies and programs that, if we take them at their word... are intended to help the poor. Unfortunately, these programs generally cause more issues than they solve... and not only create reliance on them, but actually result in higher tax burdens and SOMEHOW seem to make things worse overall.
I have my thoughts and opinions... but I think people need to make their own conclusions as to why this happens. For example... in 2009, President Obama "nationalized" the overwhelming vast majority of student loans into Federal programs. Why? The reason was because he wanted to create better opportunity for underprivileged people. Of course, my opinion is that he saw it as an opportunity to acquire more power over education and the private sector... as he wanted to do with healthcare, and everything else. Regardless of why he did this... the fact remains that it directly led to the problems we face today with mounting student debt. It didn't really solve anything, just created a larger problem in the end. In effect, the government created a problem, and then promised to be the hero and solve the very problem it created.
The bright spot in all of this... I am actually seeing people "change."
Most of my friends are left-leaning. We have too much other things going on that we generally don't really talk politics. During the Trump administration though, I was getting non-stop e-mails from them where they expected me to defend (as the resident Republican) everything Trump did. You know how that goes... we all do that. I never had any problems with that... but I generally held off from stoking the flames because they were pretty upset (though I think mostly worked up about things that weren't really issues at all... but that the media told them they were).
Lately... especially within the past 2 months, I've been getting e-mails from my friends where they are literally sending me videos (some from Bill Maher, some from people on X, etc.) where people are wildly criticizing Biden, or leftist actions. Like... one of my friends tells me once a week, "I'm tired of this **** ..." and he'll send me a link that talks about Palestinian protestors. He's "sick" of the protestors, basically.
Most of my left-leaning friends from my various circles still don't like Trump, and they still think we need socialized medicine, but on pretty much everything else... they've completely done a 180. It's been really fascinating to watch.
... I don't think they'll vote for Trump... they may even still likely vote for Biden. But it certainly means that Biden has an enthusiasm problem... which likely means that most people who don't
really care one way or another, are probably not going to vote... or may even be resistant to vote when approached through a ballot harvesting campaign.
