Budget Resolutions and Economic Situation

Is not one of the reasons for that the fact that the Government are creating lots and lots of low-paid jobs and substituting them for high-paid jobs? In particular, there are 800,000 fewer people earning over £20,000 now than there were in 2010. Is that not a catastrophic record of falling productivity? We want to stand up for the middle earners rising, not just the lowest earners.
