Scientology has gone through phases. Up until the revelation of "Operation Snow White" [1] it was oriented towards recruiting large numbers of footsoldiers into "staff" roles and set prices that made their services accessible to a rather broad "public". Notably L. Ron Hubbard had written that it was immoral to ask for donations without giving something in return so it was all oriented around getting people to pay for training and auditing.
I don't know about the exact causality but in terms of chronology they started raising prices rapidly around the time Snow White broke eventually putting the auditing route out of reach for a lot of people.
Under David Miscavige the church made a transition to soliciting donations for "Ideal Orgs" [2] and to the IAS in general. The model now seems to be to get large donations from a few whales and if there is a role for less well heeled members it is to have extras to populate the scene and look as if there was a broad-based movement to contribute to.
One interpretation is that social inequality has increased and that the plain ordinary Joe doesn't have enough money to be worth soliciting and if you wanted to build a cult today it would be oriented 100% around finding people in the intersection of rich and vulnerable. Sometimes I think 'rationalism' is all about that -- there's no point in scooping up aimless students at airports in 2025 and making them live in communal houses making money selling candles when you could make a movement which is all about getting the rich to donate money, e.g. "effective altruism". You don't want people's time anymore, it just isn't worth anything.
