Plus I don't think it would work in the long run. I've been having a hard time lately coming to terms with the fact that there is no quick fix. There's probably not much that even Mark Zuckerberg could do at this point to take Facebook in a more equitable direction. It might require a leap of insight even greater than starting it in the first place.
All of the important positive changes in history happened through organizing. It's really up to the employees of Facebook to do their part every day to make things better. If the system doesn't allow that, then they need to work to change the system.
On a personal level, I'm going to vote and donate to positive causes. But I'm concerned that won't be enough to counter the decline in education and civics that I've witnessed over my lifetime. There are fundamentals that we could work on though. For example, the US was founded on public education. I'd ask anyone reading this to ask themselves why they might favor private education over public, and how that basic idea might lead to college that is more expensive, or dogma in our political discourse. Some ideals are timeless and needed now more than ever.
