Bhaskar: To govern the capitalist state is to serve capital, whatever your intentions.
Somebody: Yeah, and to head up a trade union is to serve capital, and to be a member of Parliament of a minority left party is to serve capital, and to run a soup kitchen in an inner city is to serve capital, and to have a socialist mailing list is to serve capital.
Maybe the left should concern itself less with whether or not it's tainted by capital and more about achieving practical goals to improve people's lives. Less revolutionary rhetoric and more improved health and education, comrades.
