The second biggest problem I have with Traveller social standing is that it is used in two different ways that are mixed up with each other most confusingly. As a game artifact, it chiefly reflects social influence with -2, -1, 0, +1, +2 modifiers to skill rolls (i.e. reaction modifiers). As such, it doesn't (ought not to?) map directly to social status (Though a strong correlation is a reasonable assumption). A person could be a billionaire and have a skill modifier of -2 if he had some major odious personal habits or a reputation for mistreating widows and orphans. Someone from the wrong side of the tracks could have a skill modifier of +2 if he had a charming personality and a decent suit of clothes.
But then you have a definition that says that social standing denotes a character's place in society and a partial list that says straight out that social standing 11-15 correspond to Imperial knights, barons, marquesses, counts, and dukes. Which implies that Soc 1-9 corresponds to specific sociographic categories ranging from, say, vagabonds to squires (estate owners). Unfortunately, the MgT writers have not vouchsafed us an actual list, and as a result Soc 1-9 becomes treated as reaction modifiers only while Soc 10-15 becomes a mixture of the two.
(The biggest problem? That a social ladder that divides the lower and middle classes into nine levels and the 'ultra class'
1 into six has no levels for the upper class (the planetary elite).)
1 To coin a term for the interstellar elite that an interstellar society would pile on top of the planetary elites.
