Solidarity is a principle of social justice [0]. It's very simple, and related to tragedies of the commons. When there is some common resource, solidarity is the idea that we should all adopt common attitudes towards that resource.

I can afford to pay my rent. I have no problems doing so. However, if I were to learn that my rental management group were facing a large rent rebellion, that I believed that the rebels had legitimate complaints, and that the rental management group could survive the rebellion by evicting all of the rebels but only if I paid my rent, then I would consider not paying my rent.

Therefore, I can imagine a situation where I would not pay my rent despite being able to afford it, and be expressing solidarity by doing so.

I don't really care whether or not you're sympathetic right now to this particular cause, but you should consider the principles behind the actions that people are taking, and spend some time putting yourself in everybody else's shoes.
