For example note the quote.
Notice that is it not "paying the amount to which they are lawfully obliged to pay"...it is "fair share".The Exchequer Secretary spoke out as he gave a speech outlining plans to name and shame those who engage in aggressive tax avoidance schemes to avoid paying their fair share.
When you know how mass brainwashing via propaganda works you see it everywhere.
If income tax created a LAWFUL OBLIGATION then they would not use "morally wrong" and "fair share". They would use UNLAWFUL as the word to describe it.
Notice also that ILLEGAL has NOTHING to do with UNLAWFUL. ILLEGAL and UNLAWFUL are two entirely different things that are totally unrelated except where legislation is aligned with law...which is not that much actually.
