The people in the example I gave come from the countryside where there is not enough food, so they go to the city. What they do in the city I didn't mention. Their main idea is to get food I would imagine. After they have food, they might consider protesting, but usually, people who are starving don't have much energy to consider protesting, their main goal is to try to get food.
Now, isn't it my duty as a very privileged born person to help them to get justice, try to change the system? If you have the power to do so, we try to help people in need. However there are many things beyond our power to control in the world, and it's not our responsibility to end the suffering of all beings. This is why we need to have a certain amount of equanimity to balance our compassion to understand what is within our power to change and what is not. Because taking on a system of another country ourselves, how can we change their system? I know it's not within my power, it's not within my realm or my ability.
But I am focusing on something we can do in the world to increase the power of compassion and lovingkindness, etc. That's where I focus my energy and hopefully there will be more growth of beneficial qualities in the world. But to try to think that I am responsible for changing the regime of a particular country, that would give me a feeling of futility, of powerlessness.
I try to focus on what I can do to increase the powers of goodness in the world and try not to upset about what I can't do. However that does not mean I am not opening up with compassion to the suffering in the world, because this gives me a lot of motivation and energy to help in the ways I can. Otherwise we can get overwhelmed by the enormity of suffering, the enormity of Dukkha in the world. I am trying to see what is within my power to change and what is not. Learning how to balance our compassion with equanimity and reflecting on what is our responsibility and what is not, and that everybody is the owner of their Kamma helps me see what I can do and put energy, a lot of energy into what I can do, rather than being overwhelmed with what I can't do.
We have to try to accept that the human realm is not totally satisfactory and coming to that place of acceptance is not so easy at times. We would like to make everything wonderful and happy, but it's not in our power to do so.
