Is it also not the fault of the 99% who vote for non-Green parties who then make the laws causing your bullet points?

Waaaaaaaay less than the people who have used their power to corrupt said system.

In the 2024-11-05 US House election there were 149.5 million votes (I don't know how many eligible total), and 0.2 million voted Green.

In the 2024-11-05 US presidential election there were 155 million votes (only a 64.3% turnout), and 0.8 million voted Green.

In the 2024-07-04 UK election there were 48 million eligible voters, and 1.9 million voted Green. However, polling shows that despite the UK's first-past-the-post system, the Greens (in Feb and March) regularly polled ahead of both Labour and the Tories.
