You can kindly go fuck yourself. By assuming people not only aren't doing anything about the state of the world because they complain about it online but also assuming that they are in a position where they can do more, you are part of the problem. Especially by giving such polarized statements that simply shame people and have no clear, actionable suggestions on what to do. The system is designed to isolate people and prevent them from utilizing the power that they have to change things, and here you are, whining that people aren't utilizing their power to change things. You're just as bad as the people you're complaining about. You're not changing anything other than the number of people in the world who want to punch you in the throat.

There's a reason that historically, most protests in the US were centered around a core group made up of college age kids, up until the past 50 or so years. It's because that demographic has (had) the most free time and least financial burden. It's the reason that college is so expensive nowadays. It was retaliation against the college kids who protested against Reagan when he was governor of California. The lack of free time and financial pressure on the workforce ensures that we'll be less able to exert our power to change things.

If you actually want to help, you can help get people to the polls, especially for state and local level elections, or help aid groups that support striking workers. The reason old white people control so much of the state and local level government isn't because people are sitting at home whining - it's because their boss told them that they'll be fired if they take the day off to go to the polls, and their district is so gerrymandered that it wouldnt make a difference anyways. The racist retirees are the ones who go to every town meeting and show up to all the hearings and community polls because they have all the time in the world while they live on their pensions. So, if you want to change the world, start by driving people to town meetings and to the polls on the local election days. Fight to ensure that people have the time and can afford to exercise their rights to make the world better. Or you can keep whining on the internet like a baby.
