I agree, but only because the media is so tightly controlled by the ruling class.
If a new media platform broke out that they did not have control over, and a reasonable left third party took control of that platform, and many people ran to it, basically if, you know, you could win the lottery twice while being struck by lightning and getting hit by a falling meteorite, then a third party could actually emerge and win.
But with them owning Twitter and Facebook and Reddit and Instagram and WhatsApp and every single news station on the planet, there's just no way to communicate what the world could be like to the people who would vote for the better world.
