UK plc want s to build a new line from london to Birmingham then oop north and the natives who live near the new line are all do the nimby dance of fear.
In France they just do it, for the benefit of the people and freight.
My opinion is that Souter built his empire by aggressively undercutting local operators (at a loss) until they died, and then put prices back up, in clear opposition to the public interest and the interests of drivers who are now beholden to a single company. My opinion is shared by the Monopoly and Mergers Commission, which is rather more objective than your silly book link.
AND thats what the books says as well, but thats capitalism, where bigger companies take over smaller comapnies, just reading a book now about the privatisation of the bus and coach market, and it appears that if a small local bus firm closed down , or was sold a local competitor would buy it, with no one from outside thwe local area bidding, Stagecoach changed all that, and built up a multimillion pound company.
Thats progress.
