Bill Gates and Oprah are both billionaires. Billionaires in general want solutions that defend capital. Privately run schools that receive government funding, in addition to tuition, while also being able to set their own curriculum free from the state is certainly within their collective class interest.

Many seem to make the mistake of assuming that one’s allegiance to the US Democratic Party means that the individual is a leftist, that cannot be further from the truth. The most recent presidential election I hope would have dispelled such myths however I am not certain if that is the case. That said, the US Democratic Party is a right centrist party. I fail to see how a film with endorsements from Bill Gates and Oprah Winfrey is convincing evidence to show that this film is not rightwing propaganda. All conversations within the Overton Window of acceptability within the US are going to be right of center inherently, including films like this one.

If you think _all_ of the Overton Window is "right of center" than you are surely miscallibrated (there's even a meme floating around that describes this exact conceptual error).
