Only some companies… logically assess what you are saying: for all business, government has board representation!? How would that scale? Where would the government get that kind is workforce?
I am not suggesting but saying that the CCP has a pool of members to tap into and is able to force companies to make them members of their board. Junior members will grow older, can be board member of small companies in the countryside in the beginning, then evolve as they grow. Older members can be board members of 10+ Big companies.
