I find the tax system we have represents a compromise: You need free market mechanisms to implement price discovery for cooperation (products, jobs, etc...) but at the same time you want to prevent the formation of monopolies and extreme bargain powers.
Do you really think that the State prevents monopolies?
Also, if the only purpose of taxation is to prevent monopolies, why do I have to pay taxes?? I do not have any monopole on anything whatsoever.
No. And the reason for that is that all the ideals which come out of philosophical discussions eventually stand corrected by reality:
After a while every government is just another cooperation and acts in its self interest. States become corrupt and we have no real way of dealing with big corrupt governments. Do we?
