I think we're beyond that. The whole system is broken i.e. government, parliament, "democracy", elections, parties etc.
Really, parties, elections, government and such are just a distraction from the fact that corporations control the world.
Elections still work provided that you can get people to agree with you. It's an uphill struggle on complex issues but it's far better than a violent alternative.
What you need to look at is high finance, defence and global infrastructure corporations.
I'd be a noisy activist but I'd rather subvert the system silently and educate my children to be ethical, upstanding and to quietly have zero respect for implied authority. Better a grey man[1] than a dead man walking.
[1] from the survivalist wingnuts, but a valid philosophy: "Grey man - an individual who possesses the skills, ability and intent to blend into any situation or surrounding without standing out, concealing his or her true skills, ability, and intent from others."
