> I thought it was free money because it doesn't put a disincentive on productive work
There are 2 major and unrelated effects to taxes that are discussed in any basic economics 101 theory that I am happen to explain to you.
Sorry, I take a lot of basic econ theory for granted, even though I am sure most people haven't taken an introductory economics class. Thus leading to confusion.
effect 1: Changes to behavior/Disincentives on work. IE deadweight loss.
effect 2: the redistributionary effects of the taxes. IE does it harm poor people or not.
These are unrelated effects and are separate effects/downsides/benefits.
Do you understand how there can be 2 effects to a thing that happens, effect 1 which is bad, and that there can be a different effect 2 which is also bad in a different way?
You saying "Well what about this policy B that doesn't have downside number 1?!? Are you saying that there is nothing bad to policy B?!? Because you said that policy A was fine because it doesn't have downside 1? Therefore it must be that policy B is good because it also doesn't have downside 1."
The completely obvious counter response to this bad point is that policy B, which is different than policy A, has an additional downside which is downside number 2.
And policy A is good because it has neither downside 1 or downside 2.
Does that explain the misunderstanding that is apparent from your comment?
The fact that you brought up a head tax also betrays the point. Because you know that a head tax is bad, otherwise you wouldn't have used it as an example.
You know that it isn't the same. Although it still confuses me that you would bring it up, because you didn't jump to step 2 which is to explain the difference between the 2 policies.
And the next question, that actually matters, is the clear different between a head tax and a land tax. Which is explainable via basic economic theory.
