William Z. Foster: The Socialist parties of the world are the third parties of capitalism. They do not fight for even the most elementary demands of the workers. They are a part of the capitalist machinery for taking the bread out of the mouths of the workers and their families, the principal barrier to the revolution. That is why in Great Britain, Germany and other countries the capitalists have supported Social Fascists to head their governments. In every case their record has been one of subservience to the program of the exploiters. In practice their policy of the gradual building of Socialism has resolved itself simply into a desperate effort to keep the breath of life in capitalism. Their so-called nationalization of industry is only a covert aid to capitalist trustification. In no country have they achieved the slightest progress towards Socialism, or even made serious proposals looking in that direction. https://wordsmith.social/protestation/quotes#quote4757
