I think if you go to Scandinavia or the UK you will find the opposite. Housing is an example of a field where the government was much more active pre the 80s. Idk if the US has had the same development, but it is certainly not a global truth that it only goes one way.

Yes when you run out of money the actual interventions invariably shrink, but AFAICT the expectation has not changed.

The expectation certainly has changed. Do you not remember Thatcher?

Housing as mentioned above. There was also a time the railway was a obvious public responsibility. Similarly for airlines (Scandinavian Airlines, British Airways). Telephone companies(British Telecom, Telenor), mail (Royal Mail), gas (Gas Act 1948), iron and steel (Iron and Steel Act 1967), and electric production ( Electricity Act 1947).

If anything it is rather opposite, the moment something is privatised it's hard to get it under public control again. But even if you don't agree with that it should certainly be clear that removing something from the public sector is both possible and has happened to a large degree.
