If you are an introvert and shy away from using your voice or your presence to address inequality, there are still a number of things you can do to improve things. Here’s a starter list for you to consider.
1. Contribute money. Money is power, and giving money to groups that work to combat inequality is a straightforward way to shift power to those having less of it.
2. Vote for candidates working to reduce inequality.
3. Decline positions that reinforce inequality. Do you belong to some organization that fosters inequality? Consider resigning or asking the leaders of the organization to better balance the group so it is more equal.
4. Educate yourself. Find good sources that deal with the inequalities you see and will give you better insight into the problems and how they can be solved.
5. Amplify voices dealing with inequality. If you can, help share the voices of people trying to address inequality so others can hear them.
6. Address your elected officials. Besides voting, you can prod your elected officials to do more to address inequality. Most elected officials are interested to hear what you say and even for an introvert it is not that hard to speak up to them.
7. Educate others. This may be harder for you, but consider ways you can share what you have learned and try and find ways to communicate to others existing inequalities and how they might be addressed.
This isn’t an exhaustive list, but it will start you on your way to help push back against the inequality you see in the world.
