It really is so fucking bleak isn't it (I had a short stint in sales as my first proper job, and like you, I hated it but it opened my eyes to a lot)..

I guess the one positive in realising these things is that with it comes the realisation that the issues we face are deliberate and systemic, which hopefully leads to understanding that the solution then must also be systemic, and the more people realise that, the more chance we have at actually reaching the tipping point where enough of us band together to achieve it.
