Preamble
Ever since the October Revolution and the subsequent rise of Marxism-Leninism in most of the former Russian Empire the ideology of Syndicalism was considered "old-fashioned", "outdated" and even "dead". During and after the events of 1917-1922 more and more leftist parties in Western Europe began rejecting the ideas of anarchist ideologues like Proudhon and Bakunin, the fall of the Makhnovshchina put the last nail in the coffin of that, and began flirting with "the big three" of the Russian Revolution: Lenin, Trotsky and Bukharin. By the time Stalin got into power, Syndicalism fell out of the mainstream: slowly being less trusted thanks to the German Revolution and how brutally it was put down.
But those events are over: the Soviet Union doesn't exist anymore, China is de-facto a capitalist state, and more and more people are being disillusioned by Capitalism. Is this the time for Syndicalism to make a comeback?
Chapter I: The state and it's monopoly in Violence
To find out what makes the state so bad, we need to look back at the history of how an idea of a state even came to be. The ideas of "government", "leaders", etc. were created in Ancient Mesopotamia in regard to those who had the most grain. People naturally followed those who had all the food, and the "food owners" could become so influential that they controlled whole cities. To keep the plebs loyal a welfare system for free food was created, which was a widespread practice until the fall of the Western Roman Empire.
From the very start the state has been nothing but a monopoly. As the ages went by and weapons became more advanced they became a tool of not just war, but also a tool of suppression of people that resisted the system, which was common thanks to a little thing called "Feudalism". Peasants rising up to kill their lords and try to take the king's palace by storm were common. After that it all went downhill, with the state restricting the armament of civilians in most of the world to prevent it from being overthrown.
But even with that most countries in the world pump hundreds of thousands of dollars into the police, military-industrial complex, etc. In most of the world only the state has the right to produce so many tools of violence. It has a monopoly on violence.
