It does not pay union dues directly from sales. This must be a first order priority among activists and economists. We cannot expect the voice of labor to have the sustained power of profit until it is fed under law and custom from the same stream of trade generated money. Not that union dues alone will bring a miracle. Structures will have to be made nearly perfect to keep out the goons and the crooks and make unions more democratic and effective.
School boards are democratic, but they too are failing everywhere they grow too large.
Unions of smaller size, policed and audited the same as business, will be required. The environmentalists exist today mostly on contributions from the rich and middle class who are dunned incessantly by junk mail. Well we did win in Seattle. And the millenial holiday season is here.
