I know will refer to the constitution and human rights on this matter but If a citizen does not contribute to society, how can that citizen have an opinion on it? Ultimately if you do not pay tax, you have no need to affect the political process, and your impact will be negative to others because you will be uninformed on how to vote to improve things.
WHAT DO YOU THINK?
historically voting rights were always interlinked with taxes. this was especially the case when there was no banking cartel.
universal voting rights came also with universal enslavement by a banking cartel.
