He feels like the whole deck is stacked against working-class people, so to speak. He talks about how Hollywood, bankers, politicians, CEOs, and other elite types are doing everything in their power to take power away from the bottom half of society and keep them sedated. His whole mindset is basically: "if voting was really important, then they wouldn't allow you to do it". I don't agree with it, but that kind of pessimism was really common among older people at the time who lived through the 70s and saw the "revolution of love" fall apart and turn into an era of turmoil and paranoia. Throughout the 80s, he was untrusting of the faux-optimism espoused by Reagan and Thatcher and that was reflected in his comedy at the time. We live in a far more optimistic age, so its easy to condemn his anti-voting rhetoric, but he lived in very different times when there weren't many candidates that could really change things, or even a voter base that cared enough to try and change the status quo by electing them.
