IWW and syndicalism

Unions are helpful in teaching people how they can have power collectively, and how to wield it and organize.

Admittedly many unions now are corporate captured (teamsters as an example), but more revolutionary unions like the IWW are much more useful in regards to actually getting people to become class conscious, and more apt to prefiguraton.

An example in practice is how the FNT and CAI unions in Spain were able to organize their communities when the government institutions crumbled during the Spanish civil war, resulting in a well functioning anarchist society in Catalonia.
