That is the key point. If we have effective anti-evasion and avoidance measures, an increased rate of tax will inevitably lead to a higher yield.
We are living in very worrying times where wealth inequalities at geographical and individual levels are unprecedented. Parts of London have gross value added 12 times higher than parts of Wales. While London has the highest GVA per head of any area in the European Union, west Wales and the valleys has one of the lowest. The contemporary history of geographical and individual disparities has been truly depressing in this regard. Successive Governments do not have a good story to tell, with rebalancing promised but never delivered.
At the heart of the argument for a reduced top rate of tax is the trickle-down theory that underpins much of the now-discredited neo-liberal economics that the Thatcher and Reagan era ushered in. It was always sold to us that the newly re-empowered financial elites would spend their money and it would trickle down, and the people at the bottom would become wealthier as a result of this benevolent spending. But what has happened over the past 30 years? Inequality has, in fact, grown massively. Instead of the wealth of the super-rich flowing down, the rich, especially the super-rich, have got steadily even richer and hoarded their money. That money is not simply made out of the sweat and toil of their own good fortune, skill and brilliance, but often on the backs of those who work hard on the bottom rung but gain little financial reward for the true value of their efforts.
We often hear the super-rich whine that they have made their money, so why should they pay a lot of awful tax on it? Well, that tax goes towards paying for important services such as schools, to educate the work force of the next generation, and hospitals, to maintain the work force in good health. It also pays for a police force that keeps our communities safe, and a legal system that ensures that the law operates smoothly and in a trusted way to allow for a broadly prosperous economy and a society free from corruption. We erode these provisions at our peril. Taxes do not exist in a vacuum; they provide the services that create the whole that enables individuals to go on to enjoy the freedom of being able to make money and enjoy relative prosperity. That is what the proponents of the trickle-down effect have forgotten and wilfully ignored over the past 30 years, as the hon. Member for Ogmore (Huw Irranca-Davies) said.
My new clause would pave the way for the additional rate to be raised to 50%—a small rise of 5%—primarily because that would be symbolic of a move towards a more equal and just society. Only last month, the International Monetary Fund released a report that concluded that the more equal societies stand a better chance of long-term sustainable economic growth. Of course, the IMF is the high priest of austerity which, throughout the 1980s and ’90s, forced developing-world Governments to privatise their publicly owned industries wholesale and enact wildly free-market policies in exchange for international loans. The result was the plundering of those countries’ natural resources by global multinationals, with little benefit being felt by the poor local populations and the elites doing handsomely. It is therefore quite a turnaround for the IMF to conclude that income inequality impedes growth and that efforts to redistribute are positive.
This is the real political challenge that will face us over the next generation. That is why we should be ensuring that those with the broadest shoulders bear the burden in what will continue to be very hard times for those at the bottom of the income scale, given the massive cuts that this Government are still intent on inflicting. Let us remember that a vast tract of the austerity programme has yet to feed into the system. An additional rate of 50% would help to ensure that the super-wealthy bear the burden and pay their fair share. I urge the House to support the new clause.
