Worth a read (unless Dan Neidle brings you out in hives)

The 1970s are often described as the highest tax decade, but that’s not quite right – income tax rates in the 1940s and 1960s briefly went over 100%. However the rate of capital gains tax in those years was zero – because there was no UK capital gains tax.
It was, therefore, standard practice for the very wealthy to (without too much effort) convert their income (taxed at very high rates indeed) into capital gains (completely untaxed). An episode of Untaxing discusses the Beatles’ successful use of this strategy, and how the same tricks don’t work today. For a much more detailed exploration of the strategies adopted in the 1950s and early 1960s, I highly recommend the 1962 edition of Titmuss, Income Distribution and Social Change.
So, whilst it’s harder to find information on the tax and income share of the 1% in the 1940s, 50s and 60s, I would be reasonably confident that the 1% paid less tax then than in the 1970s – and much less than today.
Why does it matter?
It matters because the tax policies of the 1970s were a failure. They failed to tax the rich effectively. They failed to fix the Government’s fiscal problems – overall tax as a percentage of GDP was higher in the 60s and the 80s than it was in the 1970s.
The lesson of the decades since the 1970s is that the best way to tax the wealthy is by expanding the base and closing loopholes. That makes a less snappy soundbite than sending rates sky-high, but the evidence and the history shows that it’s fairer and much more effective.
