It's a doubly weak argument because Southern Korea's privatised railway companies were nationalised by the US Military Government in 1946 - and run for good, or for ill -as a state-owned national industry - until the early 1990s. It was in this period that the ROK sustained growth, as privatisation was deepened the Asian crisis took over.
The ROK also massively protected its infant industries as the Soviet Union did... .
In fact I don't even know what I'm arguing against
It's as if random lists of three have been plucked out of Moon23's ears: Korea, Singapore, Taiwan STOP Telecommunications, utilities, travel STOP Strikes, blackouts, rotting rubbish STOP Nationalisation, State ownership, protectionism
