I am a deep believer in free markets as the most efficient mechanism for distributing goods and services, creating better offerings and lower prices through competition and encapsulating risk in innovation. Unfortunately, none of these apply to the privatization of inherently public commodities that run on top of an underlying network infrastructure. This can be streets, railway tracks or water pipes - whenever there…
We tried this with the railways in the UK. In the mid 90s the tracks and signalling and most of the stations were transferred to a publicly owned and regulated company (Railtrack), while private businesses competed for franchises to offer train services. But within a few years the government was unable to resist the temptation to privatise Railtrack too. After that we had the inevitable phase of regulatory capture, followed by financialisation of the train operators, leading to position we had at the start of the pandemic where the operators were basically competing to offer minimal services for maximal revenue by subsidy farming.
In the absence of regulatory institutions that are able to withstand commercial pressures^W greed, then this approach will always fail.
In the UK, regulation of privately-delivered public services has failed due to decades of government by parties that view regulation (and public ownership) as simply undesirable.
