It's just amazing to me as I read history, that even in the darkest times in history where extreme state/government systems were set up to dominate people, the lowest serf's only paid 10% tax. makes me think how badly we are getting reamed in this country and around the world by the Corporate scum and their puppet governments.
We do have much more to take care of than in medieval times however. Roads, plumbing, electricity, etc.
Most of the things we "have" to take care of are things we don't actually need.
In addition there's the whole war thing. Of the money I give to the American government, a pretty big chunk of it goes towards killing innocent civilians in the middle east. And to Obama's remote-control assassination drones.
We "have" to pay for these expensive, complicated high-maintenance sewer and water treatment/distribution systems in densely populated areas. There are dozens of localized solutions that are not only cheaper, but do not require taxpayer money. We don't need the income tax, we just need to stop buying all this dumb s*** we don't need.
