I suggest that Ms Hodge go on a basic accounting course first before she continues to shoot off her mouth about unfairness and so on. The employees are the winners here with increased share profits, which, OMG, the HMRC will not be able to tax (because of a limit set by a government she was part of! see http://www.telegraph.co.uk/finance/budget/5195341/Budget-2009-The-10-most-significant-tax-changes-under-Labour.html).
So yes, as much as the woman has a point that a behemoth like Amazon *should* pay more tax, turnover does not equal profit, and given that Amazon has since its inception reinvested pretty much all of the revenue it derives from its operations, much to its shareholders' annoyance, this is not new. Perhaps she should persuade the current government (or her own shadow government colleagues) to overhaul the rather extensive tax code and simplify it.
