How are they supposed to wrangle corporate power, when that is exactly where their power comes from?
"Social issues" are a godsend for oligarchs because they allow for effort to be spent on issues that don't challenge corporate power. They provide a sink for democratic efforts that ultimately don't move the needle for most of their voters. It gives a pathway for "positive" change that doesn't threaten corporate power. It insidiously disempowers the people who would be most likely to wrestle with corporate power. Most of all it provides the illusion of opposition and therefore the illusion that I have representation because I have someone who has the appearance of representing my values (like empathy), but none of the substance of it.
Democrats have a choice. (1) don't threaten corporate power and focus on ultimately pro-corporate social issues that are ultimately dis-empowering (2) threaten corporate power/land owner power/Israel power and immediately have their campaign financing removed and their challengers funded.
Even if you believe that democrats are focusing on issues that meaningfully change people's lives, like build back better or CHIPS, they are doing it without challenging corporate power. Which is why no matter which regime is in power, it feels like democracy is in decline.
Then you get sad, because you realize there is no way to get actual representation for the issues you care about other than to run yourself, but if you ran explicitly to challenge those in power, those in power would fund your opposition. So then you realize that it's hard to get into power without expressing loyalty to those who grant power, and then you have a cogent explanation for why things are the way they are.
