I quit my (good paying) job to burn through my savings and start my own company because I want to fix this, so it's not everyone who behaves that way :)
I left the NSA after 4 years because I didn't want to support some of the things going on there. Can't dismantle it, but can at least not contribute.
Look into B Corporations and read the last third of the book Lab Rats. You can make your company serve society and it's employees right without adopting shitty cultures that breeds suicides, pissing in bottles and burn outs and still make huge profits.
