Sell assets, privatise; sell assets, privatise.
Use public money to build something then sell it to the private sector who will sell it back to the government or the public at a higher rate.
What's not to love?
I mean, really, anyone who claims that privatising assets will not raise prices is a liar and anyone who believes them is an idiot because the simple truth is that public services/utilities can run at much lower profit margins than the private sector.
This is why the NBN was so important - there were many, many areas that were poorly serviced by the existing providers because those locations were not 'commercially feasible' to install high-speed connections. A government (i.e. public-owned) provider is able to run with very slim margins - or even at a loss, subsidised by public money, if it is important for the economy that the service be widely and cheaply available (like transport).
We get told that selling assets is necessary to invest in infrastructure but that falls down when you know that the proceeds will get thrown away through poorly-managed, wasteful, gold-plated contracts that balloon out and act as little more than ways to funnel public money into large private pockets. And, of course, whatever infrastructure we end up getting for our money will just get sold to the private sector later anyway.
There's a reason companies like government contracts - they are nearly inevitably far juicer that those in the private sector and the contracts themselves are so poorly managed that they become a license to print money. Overruns and failures just mean more money and there are almost always nice, fat maintenance contracts, which can also balloon out.
