I often see opposing sides that have a lot more in common than they realize. My uncle once told me that if you accept a truth entirely, that truth becomes a falsehood and you become a fanatic. I'm still not exactly sure what I think about that statement, but I do think we often agree a lot more than we admit when having idealogical arguments.
Most of these thoughts come from my dad. He had quite a few talks with me about anger. One of the main things I remember him trying to get across to me was to take a hard look at myself when I was angry. Over time I have found that extremely useful. I am not a victim. I am responsible for the reality that I create. I can't say that this applies to you, but it is the way I see things for myself.
He also told me that if you get good at making excuses, you don't get good at anything else. Please forgive me if I come off as an asshole - I often do, even though I really don't want to. I want to spread happiness and love, but some days I have anger and I have learned to express that anger.
The idea of being a capitalist and communist is not my own. Neither is the saying about money being a great servant but a horrible master. Both of those teachings come from the great master known as Omraam Mikhael Aivanhov. Please look into his teaching if those ideas intrigue you. He never wrote any books but many of his students transcribed his lectures so that now there many books containing his teachings.
