I want to help but don't know how, I started looking into volunteering hoping to find a cause to commit to.

Familiar feelings.

I've struggled with some sort of "Messiah-complex" once (after LSD-trip, the complex withered away with time; dunno if that's essential to notice), wanting to give a little bit of my time to help everyone I met and who seemed to be down. Seeing queasy people was like all the complex feels they had inside them became mine. For real. I don't know if I was in a psychotic state or what but I felt so tired and helpless seeing people who seemingly were feeling bad. I wanted to just be there for them, even for a little moment. Share something with them. Give a glimpse of caring, a glimpse of something that goes beyond our usual grey ordinary life. Remind that there are people who feel for them and who care even if it doesn't usually seem like that.

Maybe I was delusional, maybe not.

It's just that there are so many of us, everyone having their own ideals. I find it a bit dangerous to think one person could help everyone, I mean at some point it can become "I know better than you what you need" -kind of conduct.

That's why I've came to the conclusion that we shouldn't try to carry the whole world on our shoulders, but rather help via little things here and there. It is certainly enough that we only help the inner circle of ours, or as many people as we have enough strength to help. Helping everyone is not necessary and maybe not even preferred, because we can't go inside everyone's heads and know what's the ultimately best for them.

Maybe that's why INFJ's are generally not seen as good leaders? We might be good and constructive interacting in one on one -interactions but "controlling" a big group of people can become fatal. I can't help noticing how many "evil leaders" (even though they probably believed they were being ethical themselves) were typed INFJs. I don't think that's a good position for INFJs, I see too many ways how that can go wrong. It's not set in stone, though.

But I can totally relate to your thoughts. It is true there are structures in the society that push people into misery. And sometimes people pass their own negative feelings onto other people because they've been so hurt themselves and know no other way of living. Perhaps mostly unconsciously.

I have no desire for money, social status or power

It's funny I felt this way even as a kid. I remember having a conversation with my family on future careers and plans maybe at the age of ten. I couldn't understand why it was so important. I said I could work as a cleaner as long as I had enough money to eat and pay bills and was happy otherwise. Now I know being a cleaner is not my thing (too stressful) but the same "idea" still holds true. My mother tried to temper me down. Especially when I said I might not want kids. I'm not sure if I want kids, but the connotation of the conversation seemed to be that having kids is some kind of one pillar towards greater happiness. And I didn't agree it's universally like that.
