Some of us pay the tax that on the face of it we are due to pay rather than try and find ways around not paying some or much of it. Many of us have no means of not paying what we are asked to pay, why should some think that just because they have the wherewithal or tools available to dodge much of the bill, that somehow that it is morally OK for them to pay a smaller proportion of their income to the taxman than others.
it's even worse when some then breach about austerity or cuts to services
