I'll also add that as a "campaigner" working for someone like change.org, you can expect to make less because lots of people want to work in the these activist roles. It's similar to how game developers are paid less than b2b saas developers.

Always seems a shock to HN when the jobs that everyone wants that don’t require a very technical education tend to be on the low end. Well at least for the campaigner role.

The median salary of $50000 still seems a bit low to me considering how real estate must be pretty expensive in Manhattan. An okay-ish 1-bedroom apartment seems to be around at $2000 a month, which amounts to almost half of your salary (and I haven't really delved into the living costs of that area!)
