You mention responsibility, and I think that's exactly what it comes down to. Just, in a different way in my opinion.

As the saying goes, with great power comes great responsibility. Yet here we are, handing a select few people incredible social, economic and political power, with little to no strings attached. No responsibility is expected in return. No accountability is asked. It is a one way street, enabled by the systems we've built and allow to exist.

So yes, you are right. It is in part everyone's fault, and it is in everyone's responsibility to act and be the change this world needs. The way to do so is by making it a fair trade again. The few we give give all that power to, they must use that power responsibly, and we must hold them accountable if they don't. Allowing billionaires to keep taking, allowing them to corrupt politics, and to exploit their workers despite all their wealth, we have to stop that.

Hence the sign and the message on it.

Again,its no ones fault more then like you Said, responsibility.
We never gave [them] power, nor did we choose any of them
We Are not letting anyone keep power
Its been out of our hands what other do,and what we do is
We been enslaved Rich and poor this whole time
Its spiritual most of the war, where anything in form is thereof?
Again,its how Are we walking through the fire?
There Will be fire, poor or rich
