I was in a project based learning school and many people are not really able to be accountable, so I'm wondering how they can tell if anyone is doing anything productive?

Both incidents in the United States had to do with African American Rights a and "Wrongful" deaths by police officers. They are different in one was much more justified than the other. In the first case the public misinterpreted the story and the riots and the protests got out of hand. Whereas the other incident had a video that was given to the press that gives Americans a concrete way to make opinions on the matter.

Another point is wouldn't hard for someone to get a successful job or go to college if one is following no structured curriculum.

Social media helped Ukraine because it helped people get organized and make a plan to protest the Russian government. Right now they are still very mad, although there is no war yet.

The Venezuelan people are unhappy because the inflation, crime, and lack of materials. The government is also not doing very much to help the people.

Many major protests in history happened without social media, mostly because the issues were so important that everyone wanted to be a part of them, but it wonder if some of these outrages would have happened without social media, and I think they would.
