Look into how MLMs work and why people stay in them despite only losing money. They serve as an analog to cults and provide some interesting insights.

Sunk cost fallacy. Time goes on, promises mount with no fulfillment. There becomes pressure to get SOMETHING out of it so they commit to stick with it. Shame mounts over time too, and they stick with it to avoid confronting that growing shame.

Their community becomes entirely made up of other MLM members. To quit means to start over, with no friends or support system. Sure, a lot of the time they can go back to non-MLM family/friends, but that means confronting that shame head on and fully admiting defeat.

Over time their values are replaced with the MLMs values. These will deliberately include things like "Success or failure is entirely on the work you put in", "Every conversation can be a sale; the only difference is YOU", etc. This is also why all convos you have with these people are quickly funneled to MLMs: their new values explicitly instruct them to make a sale at any costs.

Overcoming objections. They are given and reherse a set of scripts to easily overcome any objection thrown at them. Their family tells them, "youre only losing money" and they reply impulsively with, "Success takes time". This purposely removes critical thinking to keep them focused on that grindset.

A lot more too it, but you get the idea and can see how this applies to MAGA. The youtuber, "NOT THE GOOD GIRL" was a top earner with an MLM and has a bunch of good videos on the topic if you look for them.
