First let me say that I do not believe in the current fascist system we live in where corporations are in bed with the government. Bit I am not going to respond to this current problem with an answer like socialism or communism or collectivism. We should respond with true capitalism.
With that being said, just because I am a consumer, it does not give me any right to demand your profit.
Example. If I make a skateboard for 5 bucks total, and sell it for $1000, as long as there is no fraud then you have no right to any of my profit. Do u agree or disagree with this principle?
No, because the only reason that you are afforded the standard of living that you enjoy is because of the economy and the social monetary system. Social systems exists because they improve the standard of living of all the individuals participating in them. And, social systems require management and maintenance in order to continue to function.
And the reason there is no fraud in your example is because we have a legal system that defines and enforces the illegality of fraud. The reason you can purchase materials for 5 bucks is, in part, due to the enforced social systems including highways and airspace. From the outset, your example demonstrates why taxes exist.
The question isn't whether the government should collect taxes. The question is how to optimize things.
To begin with, monopolies are illegal. The reason they are illegal is because they have such market leverage as to be able to control prices that otherwise would be controlled by the market.
We have a Federal Reserve that manages the money supply. The reason is to optimize the utility of our money. Left to it's own devices, the private banking system would kill the economy. Even regulated as they are, they still manage to injure the economy.
Technically, according to the principles of micro economics that wingnuts continuously espouse, you shouldn't have any profits. A functioning free market results in no profits because where there are profits, new competition enters the market.
