Your perspective is deeply troubling and painful to read - I feel for you and hope that you may find a way to change how you see the world. I'm older than you and I feel very lucky that I've developed - over many years of spiritual and psychotherapy work - a profound sense of optimism and positivity.
I think you could get there too. I hope so, because your current thinking is helping nobody and could lead you to lose hope and harm yourself.
Without talking about spiritual psychobabble, let's break down some of your (false) beliefs.
Someone becoming a billionaire is not illegal, or even unethical. It may be offensive to you as you struggle to pay bills, but this person has not stolen anything from you and is not in possession of anything that you have any rights to. You're confusing your offended feelings with some ethical principle and the two are not connected.
Most billionaires are in fact very optimistic people. They do not seek bunker living as the world burns. Most of them seek to make the world a better place.
We have a larger middle class in the human race today than at any time in history. For millennia we have had kings and peasants, with all the power concentrated in .001% of the population. Kings were much more cruel and powerful centuries ago than today.
The western civilization portion of the human race is a beautiful model that has lifted 2 billion people from poverty to middle class.
We are all doing so much better than we think. I recommend cutting the TV cable and unsubscribing from all the digital bad news. It isn't helping us. Problems that we can't fix are problems we need to remove from view and sever ourselves from any responsibility or blame. I didn't cause climate change, therefore I refuse to lose any sleep over it. It will get fixed.
Life is rich.
