Taxing situation.

Tax avoiding, or tax dodging?  Are they the same thing, why are we so keen on stopping them, and how the heck can we do it?
I am sure there are those amongst us that think paying your tax is a moral obligation, is cast in stone and that any attempt to not pay your due taxes is wrong.  I am also sure that in the same street lives someone who will go out of their way to pay as little tax as possible by whatever means available to them.  So who is right?
The moral case for paying taxes is admirable, and those that think like that are probably anti-capitalist verging on a communist ideology.  I hope they give most of their remaining wealth to charity, or at least spread it out amongst the needy/local council/NHS (delete as appropriate to your region).
However, the tax avoider is obviously (?) selfish, has no regard for the moral case, and is probably on the right wing of the political spectrum.
But here's an interesting fact - both types of people are doing things in a perfectly legal fashion.  If you can borrow money froma rich relative to fund inheritance tax, then it's possible.  The thing that irks people is that luxury is only afforded (or course) by those that can afford it, and the hypocritical newspapers stoke it up when their proprietors are probably doing exactly those things that they decry as 'immoral'.
So what is your average man in the street meant to do?  I know, whinge and whine about the rich kids, then try and pay the plumber in cash.
