I dont know if this will help but have a look into it.
I came across a document a while ago called the charter of fundamental rights of the european union. I did a bit of research on it and found out it was passed in 2000 and came into force in this country 2009 with the lisbon treaty. Article 15 reads like this.
1 Everyone has the right to engage in work and to pursue a freely chosen and accepted occupation.
2 Every citizen of the union has the freedom to seek employment, to work, to exercise the right of establishment and to provide services in any member state.
To me this is stating you can work tax free as a man but as a citizen you can only work through the employment contract and thus be taxed.
if any body has any takes on this i would like to hear them as i value everybodys opinion.
When a system which denies the existence of basic human rights, fear tends to be the order of the day. Yet even under the most crushing state machinery, courage rises up again and again, for fear is not the natural state of civilised man.
