So let’s agree that these are quite literally generalities. Can we start there. You are not speaking about literally any specific historical event, you are talking in generalities.

Aren’t all political theories like this?

Wow would you look at that, cherrypicking me listing examples of political theories becoming what they did not intend because politics is complex and theory vs implementation actually matters? Gee golly.

Communism gives rise to privileged ruling class and tends to take worker’s rights away when in theory it is supposed to equalize and support worker’s rights, planning an economy to distribute goods equally creates inefficiencies

Soviet Union. Ousts the bolsheviks, creates a concentrated single party that lived above regular folk : https://en.wikipedia.org/wiki/Lavrentiy_Beria best example.

Democracies create plutocracies

The United States golden age: https://en.wikipedia.org/wiki/John_D._Rockefeller

Fascism leads to cronyism

Fascist Italy: https://en.wikipedia.org/wiki/Gianni_Agnelli

Anarchism leaves gaps for might makes right-thinking

Anarchy never holds long enough. Best example you can find are the Makhnovists https://en.wikipedia.org/wiki/Makhnovshchina. Unable to assert strong central power they were overwhelmed by the increasingly developing Bolsheviks who had much more stable central authority. Their lack of control opened up space for a more central-focused entity to overpower them.

Monarchies claim divine right and then falls to civil war and assassinations who then claimed the same divine right rule

Are you fucking kidding me calling this a generalization?

So let’s agree that these are quite literally generalities. Can we start there. You are not speaking about literally any specific historical event, you are talking in generalities.___

No because they’re not. Most people understand this about politics.
