So what would have happened if MPs' pay and perks had been linked to inflation?:
An MP’s allowances in 1975, of £3,200, would have risen by 2007 to £19,367 if RPI inflation had been applied. In fact the actual figure was £90,505.
It is not just the income tax burden that has been lifted from the rich. Other taxes the rest of us pay have been waived through circuitous bypasses. The Daily Telegraph reported that a third of houses sold for more than £1m dodge paying stamp duty, costing £1billion in lost taxes (i.e. saving the wealthy £1billion in taxes). This wheeze is pulled off by placing ownership of the house into a company. Instead of selling the house, paying 5% stamp duty on the property transfer, you sell the company and pay just 0.5% stamp duty on the equity transfer. And for an annual fee of £30,000, the government sells around 5,400 non-doms the right to avoid tax on overseas income that the rest of us have to pay. These 5,400 each paid an average £1million in tax on their UK income according to the Treasury, a tantalising reflection of the amount they manage to avoid by paying what is to them a paltry £30k protection money to the treasury. All strictly legally.
