>Systems are designed for humans
They also happen to be designed by humans, and if you're just begging to have the system fix people's beliefs about corporate greed for you but don't think people themselves are at fault I have no idea why you'd think the systems would be fixed.
Always these complains about corporations or systems or institutions, the responsible person is never "I". If you're unwilling to take responsibility for your institutions why do you think they'd fix your problems? The beauty is people always get the institutions and rulers they deserve, it's not some mysterious system that allows these things to happen, it's you and I.
This doesn't sound like a meaningful critique. You're basically arguing for a culture-first approach to a systemic problem, but insisting that that culture should be one of individual responsibility. I contend that it's exactly that culture that divides the oppressed and justifies exploitation. You've decided a priori that people get what they deserve. I see injustice and try to spread understanding of how our systems create that injustice in hopes that people will change these systems to rectify them.
I'm not at all opposed to the concept of personal responsibility and accountability. In one's personal life it's important to be responsible for yourself. It's also important to understand the context you exist in, and how your actions affect others. It's bad to, say, litter on the streets, and I'll reprimand someone interpersonally for doing so. But if you live in a world where a company comes by and dumps truckloads of trash into your park every week and your government lets them, no amount of personally refraining from littering or scolding your neighbors will get you a clean community. In this case those who need to be held accountable are whoever decided on the dump-trash-in-the-park policy and whoever was supposed to stop them and didn't, and the only solution is a change of policy and creation of accountable enforcement mechanisms.
