I’ve known priests who regard themselves as collaborators with useful laity given a rough ride by people who insist they mount a pedestal so that they can be seen creeping to them.
I’ve also heard it advocated that lay people help catechise lay people - long term. Those things aren’t popular with the people that consider themselves “in”.
Hence a huge factor reinforcing clericalism is clericalism by proxy. Dysfunctional manipulators pretend to be subservient but get what they want out of the system. Then full-on predators have an easy way of getting in, by being cronies of the cronies.
Naievety about this is fostered by the Ancien Regime French who got it from the Louis XIII-XIV-XV style Berulleans who passed it on to the global Irish as unfortunately the English Catholics had been too weakened to help

. The combined Ancien Regime and global Irish influence is strong in the St Lawrence-Great Lakes area with results we have sadly learned. Also the Irish influence in Australia. I am very very sad about it all as I survey it all through the internet. I think the Irish influence would be much much better if it wasn’t for this.
As I have picked up on this in recent years it explains things we always thought queer about Catholics outside the family as we were never close to clergy, it wouldn’t have occurred to us to be.
Clericalism particularly operates when clergy pretend to be friendly and relaxed and “good craic”. It’s called people-pleasing.
Clericalism whether wilful on the part of the padre or imposed by diseased laity is a major factor in clergy loneliness and breakdowns.
I’ve seen most of the above things in person and read about the rest, in large amounts.
