You're all great and we're all in this together fighting for freedom from these large companies. Your value isn't defined by the salary your paid. We all make rich assholes wealthier while we never meet these people (that's how they want it).
You're just a resource to them so don't work so hard. Find what freedom means to you and embrace it. Don't work 8 hour days, take breaks, your boss is just another person (who hopefully hates work too). If they fire you, it means you were in the wrong place and you will find something better.
The “American Dream” is a lie that's told so you believe you can escape the trap one day (you won't). But now that you know that, you have a lot more time to get whatever that thing is done, so take breaks.
Stay true to who you are. Stay kind. Give yourself grace. If anything sounds greedy or unethical it probably is, go with your instincts.
