Essentially the iwca have given up on the workplace as the primary source of class antagonism & re-orientated itself in a defined yet unspecified geographical area. The Working Class no longer come into being by their work activity but by where they live. This means their experience of capitalism ceases to be a direct political one but & instead becomes simply a social one, or a means of winning measures against The Council/Local Government. The Council/Local Government thus replaces capitalism as the class enemy. Long term of course the iwca are building party political support, that, as with all leftism, is the motivation behind its methods. In the mean time people are encouraged to accept reformism as a way of empowering themselves.
The one & only progressive thing about the iwca is its structure, lifted almost completely from anarchist organising technique. No surprises there then.
Again with all leftism, old & new, the need to control is paramount. As i've said before 'rule' is not in there accidentally. If the iwca was genuinely interested in the needs of working class people beyond political capital, then you'd used the slogan 'working class self-organisation as self-emanicipation'
But if that was the case, we would have no need for 'parties' would we?
