Petras does an excellent job of exposing how representative democracy functions in Greece to serve the governing class. Of course, the situation in Greece is only an example of how representative democracy is used by governing capitalist classes to fool working people into thinking that their governments are legitimate.
His concluding paragraph is very significant:
For the vast majority of Greeks there is no future and no solution in the existing system of street protest and parliamentary politics. The latter ignores the former. This impasse raises the question of what kinds of extra parliamentary action are necessary and possible to end the rule by de-factor imperial rulers and kleptocratic collaborators.It seems to me, as a general strategy, that the solution lies in thinking globally in terms of working class consciousness and connecting with workers in other nations, and acting locally. Working class activism must become globalized to meet the challenge posed by globalized capitalist elites.
