I would argue with that looking at Argentina. I do see however there is not enough data to be biased against any side, but disruptive changes in management are in my perception more effective on changing the status quo. Achieving change against current incentives with politically mindful measures I'd say is very time consuming and slow. In regards to your point I agree that treating public services as companies that can't be running at a loss is been demonstrated to be bad, but there is a fine line between trying to make public services profitable VS trying to make them more efficient.
