The
Socialist Labor Party was founded in 1876 or so, but it wasn't until 1890 that it began to formulate it's Marxist-DeLeonist idealogy. Many leftists today discount the Party because it has never supported foreign state capitalist governments, dictators and aimless reformists. Also, the SLP has never absurdly supported the Democratic Party as others do. The Socialist Labor Party has never advocated anything other than the purest definition of socialism, which is as follows:
"...that social
system under which the necessaries of production are owned, controlled
and administered by the people, for the people, and under which, accordingly,
the cause of political and economic despotism having been abolished,
class rule is at end. That is socialism, nothing short of that".
It is the misguided leftists who cannot accept such a definition. But the SLP has never been irrelevant. They are the
only US political party that has refused to be swayed by money, either foreign or domestic. The SLP have always been on the side of the working class, period.
Check this party out for yourself.
