@Theriac @mrundkvist Its not so simple. See this graph of UK rail use: https://en.wikipedia.org/wiki/Impact_of_the_privatisation_of_British_Rail#/media/File:GBR_rail_passengers_by_year_since_1830.png British Rail thought its job was "managed decline". Private operators thought otherwise. And compare UK private rail with German nationalised rail: https://zbir.deutschebahn.com/2024/en/interim-group-management-report-unaudited/product-quality-and-digitalization/punctuality/
Telephones run by the GPO were a national joke. You had to wait months to get your phone connected. Connecting any 3rd party equipment was illegal. Today I have multiple companies competing to lay gigabit fibre to my door.
