I will tell you something that will make it worse and that will make it better too. Your body, and that includes your brain, has all sorts of ways to do negative feedback on overly-stimulated processes. Virtually any hormone that has any relationship with the pituitary will block it back.
The same goes with what you are feeling. This horrifying sentiment of guilt, helplessness and a painful understanding that something is deeply wrong with one part of society living in luxury, one part of society believing that through hard work they will achieve a lifestyle of luxury, one part of society trying, with herculean effort, to pay the monthly bills, and one part of society dying like so much garbage on the side of the road is called empathy (you know that much). Not that that helps you in any way (have you noticed I write a lot of things to you without really helping you, ever).
But the more poor people sleeping on the side of the road you see, the more desensitized you shall be. That image will send a message to your brain: "We are about to have an upsurge of empathy. Empathy leads to unnecessary neural stimulation. Neurones, be ready. Drop dead. NOW."
And that is exactly why you talking to all those people who work at your company would be a complete loss of energy and time. And that energy you would have invested in sharing your view is energy you would not have invested elsewhere. What would those people have answered? Platitudes that have been taught them in their schools to maintain a social system with very rigid social classes.
"Why am I monster when I don't give money to the homeless (it is not about YOU giving money to the homeless, it is about society being broken and the homeless being a symptom of that)?! I am not a charity!!!"
"Well, I first help myself (that Porsche you are driving, that Rolex you are wearing, those are not helping yourself, those are flashing your "hard"-earned money - in today's society, it is not by working hard that you make that much money)! I work hard, I deserve the best. Why don't they get a job?!"
"Oh, I do some volunteering. I do my part. (Which doesn't solve the problem, but makes you feel better; just the cherry on the icing that is your unnecessarily obscene salary: "Look at me. I am rich. But a good person. Though I don't need to be. Because I am rich. At the top of the social ladder.")
Would you honestly lose your time listening to this?! These things are being said when you put your brain on autopilot!!! They are not an invitation to discuss society. On the contrary, they are a wall being put between any valid arguments you might bring to the conversation that might shake their beliefs and make them, good God, feel bad about them being an integral part of maintaining these social constructs that victimize them.
At the end of the day, humans are monsters. It is not their grasping for more, their trampling the weaker underfoot, their cold indifference to suffering that makes them monsters, though. You can see that in the animal kingdom. Imagine if a lion cried every time a lion cub died of some disease, instead of producing another one (I am saying this, but animals do grieve; bad example)! What makes us monsters is the hypocrisy of not acknowledging that we only take, without every truly giving, and that we rather die of overconsumption than actually giving our surplus to those who would need it more.
I won't expand much on why you should NEVER, in a professional setting, go against the flow and express opinions that may not be well-received, as outspoken as you may be. You do not want to end up sleeping on the side of the road, with nothing but a newspaper to cover yourself. You might think I am exaggerating, but don't forget that whenever a new employer will look at your resume, he might call your former boss and ask about you. You do not want to be called a "Debbie Downer", that is more damageable than being called a corporate thief, nowadays.
