Because it's incorrect. No company pay taxes on their revenue so the comparison with individual tax payers is completely wrong. As our bloviated friend above says, it's quite probable that the £72 million profit figure they announced last year was the result of accounting chicanery, and paying 7% on what is already probably a lower figure than is right is pretty shocking in itself. My question is why did she not focus on what is factually accurate rather than make a false and frankly absurd comparison to try and make the situation even more ridiculous? Given her background it's hard to believe she doesn't know how companies are taxed, so it just makes her look dishonest.
Number 25 and I had a debate the other day around austerity and he quoted the 120,000 extra people that have died since the financial crisis. It's a figure that has also been used by Corbyn to make a point about the horrors of austerity. The problem is that the authors themselves make absolutely no link between government policy and the figures they calculated. It's quite possible that government policies have played a part, but given that the authors themselves pin most of the blame on excesses of alcohol, tobacco and food (and a paucity of exercise), it's a factually incorrect link to say that the Tories have killed 120,000 people.
It creates the impression that Labour are quite happy to lie about stuff to make things sound absolutely terrible, and I wonder why that is? It's no different to the playbook used by the right to chastise immigrants or Muslims. It's wrong.
