Yes - high inflation (i.e. too high, not 5%), substantial currency devaluation (not hyperinflation but worse than a mere annoyance), and especially high unemployment - higher than we have now under the market-focused orthodoxy. But it needs to be compared to a useful control. For example, if it's limited to the 1970's, it would be hard to isolate from the impact of the oil crisis. And if it's limited to the US/Britain, you need to explain why the high-spending tiger economies can be discounted.
