Mmmmmmmmmmmmmmmmmmmm.............. as I see it that is not quite what we know as tax-avoidance or even tax evasion; that is simple graft and corruption.
I will agree that this does not happen so often or so overtly in Britain, but it certainly DOES happen here too.
The "slush-funds" and the "backhanders" have always been a way to grease the wheels of industry here even if these sneaky deals are done in darkened rooms and are never laid against tax.
I do not think that we ordinary mortals on the streets of Britain know the half of it here.
