If this was true then every major navy in the world would have to have the senior specialists swanning about in glamorous comfort demanding balconies for their cabin suites.This makes me wonder about something else. If you are paying your star engineer 12,000Cr per month, he won't stay in a medium stateroom because it is below his SOC. Look at the Standards of Life table on page 98 in the CRB. If we assume that only 25% of his salary goes to pay for standards of living, that still puts him at 3,000Cr per month or SOC 10 or 11. A person like that is not travelling in a medium stateroom.
Part of why they’re paying him 12k is to make up for the conditions on-ship. The standards of living thing is for guidance: I know that this is calculated to make you furious but it’s not a hard and fast rule that means that when a soldier gets promoted to captain he refuses to live in a tent any more.
As a Scot from the north-east, I know a bunch of guys who work on the oil rigs. They get paid extremely well. They live in cramped conditions for two weeks out of every month.
