True enough.
I don't see increasing income tax on people earning £70k+ as unreasonable TBH. The Tories keep banging on about how there's no money, yet they managed to find enough to cut the top rate of income tax, increase the tax free allowance, and raise the threshold for higher rate taxpayers. Some of their adjustments have been the right decision, but they haven't been balanced with tax increases elsewhere.
If we want good schools, an effective health service, adequate care for the elderly, the disabled, and mentally ill, then we're going to need tax rises. Those tax rises will have to be placed on those who are thriving; increasing the tax burden on the poor is a disincentive to work and will only increase the in/out of work benefits bill (the inverse of what we've seen over the past 7 years).
It sucks for those earning £70k+ per year. But the alternative is that our public services get progressively worse.
