There seem to be two broad explanations. One is that the rise in economic activity has been associated with less desirable features such as increasing inequality and insecurity. There must be some truth in this. The combination of very low interest rates and quantitative easing has reignited the housing boom, and there are suggestions that prices could rise by another 10% over the coming year. The more expensive your house, the greater the increase in your wealth, and the greater the corresponding rise in inequality. As for insecurity, there has been the growth of zero-hours contracts, now being targeted by Labour, and the rise in self-employment.
