This poster clarifies that they're not anti-capitalist, but I think that this still demonstrates the radicalizing power of seeing the dysfunction of our system happening in real time. This is a big part of why the WSB crowd is so jokerfied - they know that the alleged "risk" taken by capitalists is a rhetorical trick, and that the real players in this economy will be bailed out by the poor every time. It just needs to go one step further in its analysis, and see how the poor are leveraged in every part of our society to benefit the wealthy - whether it's by fighting their wars to secure access to cheap resources or how the violence of border enforcement keeps cheap labor in their factories - in order to be real class analysis and not just a weak condemnation of the government for not regulating hard enough.
There are many ways to take the step from "capitalism is OK if it's done right" to "yeah, capitalism just doesn't work," but the easiest is asking what happens to regulations over the long haul.

Because moneyed assholes (but I repeat myself) can buy political influence, you get regulatory capture. Even if the regulations you place on capital originally work, over time they get hollowed out, rolled back, or the enforcers get bought off. This is the inevitable long-term result of any system where a society's wealth isn't democratically controlled. Capitalism will eventually corrode any restraints you manage to slap on it.
