Not the grand treasurer your local lodges treasurer. My lodge only has a handful of active members and the secretary still gets $300 a month and the treasurer gets like $30. Its read off in budget meetings.
Idk how international masonry works or what they stand for but if there are still only 3 signers per petition and they still only have a handful of petitions per year like my lodge then it isn’t that different. A pyramid scheme implies that the only reason for joining is to make money and why you described indicates that there is very little money being offered and it wouldn’t be offered to everyone. That isn’t a pyramid scheme. Using derogatory language to describe an entire class of people is prejudice..
