William Z. Foster,
The Bankruptcy of the American Labor Movement
(1922)
“ This drain of the best blood of the trade unions begins by enormously weakening these bodies and ends by making impotent every branch of the labor movement as well; for the welfare of all Organized Labor, political, industrial, co-operative, educational, depends upon the trade unions, the basic organizations of the working class, being in a flourishing condition. Dual unionism saps the strength of the trade unions, and when it does that it undermines the structure of the entire working class organization. ”
