I saw this article on the desperate plight of private sector unions in the USA (although public unions have their problems as well) which details how the AFL-CIO is attempting to expand its membership base. I thought, you know, if a union could get an exemption from POR-care for its members, it could massively expand itself by providing that exemption to new members. Start a shell company that hires people for, say, $100 / year, unionize the “employees”, merge that with the original union and boom! Massive membership win!
P.S. This is an illustration of this point.
