looking for causes for the mess we are in? Don't be so naive as to blame the political parties or elected officials.
The distraction of electoral politics has been working very well for oligarchs for a long time. The short memories of the public makes each round of insult seem new. Pick any "issue" you like and you will be able to understand how this works. In fact the dissection of their control over us into isolated issues is one of the most effective parts of the ploy.
By breaking the complex reality we live in into isolated issues the control of our minds is simplified. These issues can be renamed and dressed in new clothes and paraded around for everyone to get excited about. Our system of elections is built around this tool of oppression.
As I asked above, pick your favorite issue. When was this first a problem? Don't neglect history or you will miss the entire point. Of course single issues can be lumped into categories like "Civil Rights" and "War" and so on.
Strip away the purposely distracting rhetoric and the same core problem is laid bare. How much control do you really have over your own life and how much choice do you really have?
It has been said that cultures that have no form of slavery have no need for the concept of "freedom". This was dealt with nicely by European colonialists. They were used to enslaving others among them in one way or another. A particular way of enslaving people arose as colonialism grew out of bounds. It could be made more total and cruel by using racism as its basis.
Genocide also was easily carried out with this kind of dehumanization of native peoples. Did you ever wonder about how the other forms of slavery were made tolerable by comparison?
Fast forward to today and look at where we are from that perspective. People have been made to believe they are "free" because they can own things and do things they want to do. Not everyone but enough to make the myths thrive. To prove you are free you can even watch institutionalized oppression of those less "fortunate". You even get to waste endless time and energy voting for your masters.
No, don't blame Trump for the hate that was there waiting for him to come along. It reminds me how the poisons in our body sometimes come to head in the form of a boil. Don't blame the political parties for being part of the corrupt oppressive system. It is built very carefully on racism, religious hypocrisy, and the idea that some of us can get to be bosses.
Why has it not dealt with real problems? Because dealing with them shows the clay feet oif the oligarchy. They only know one game and they play it very well. It will end in the collapse of "civilization" and the planet will be freed of its cancer.
