Taxation is slavery - full stop. A 50% effective tax rate is not "50% slavery" because freedom is not fractional.
If you don't have a say on 50% of what you make, you don't have a say in what's left because you can't make the same decisions about it that you could and would if you kept the other 50% as well.
About the fallacy of "public services", chattel slavery victims also received "services": they were fed, clothed, housed and even protected against external aggressors and provided with order and dispute resolution methods internally. Some were even taught to read, count and more. All were taught English and evangelized. All "in exchange" for their labor.
A socialist's paradise, in short. nostr:note1jaa58x5d2mw3hueg2qgl627gdsd479lz4ctztpmg75cn88asrcqs0rhxaa
