Thrawn rose to his position of power because of his merit, not because of who his parents were! Having a High SOC score is based on who your parents were, not how smart you are.
I'll give you an example of two Georges, George Washington and King George the Third, one led his troops into battle, the other sat on his throne from across the Atlantic. Now would you say that King George the Third, if we were to do a Traveller character of him, would have a higher SOC score than George Washington? What good did King George's high SOC score ever do him, it didn't win his war with the American colonists now did it!
George Washington came from gentry through his families purchase of land and forming relationships with the elites in the colonies, he didn't come from the commoners.
This also highlights what Soc is measuring, as even if you have high Soc it doesn't mean you are a noble.
The vast majority of the Soc ladder are those in service to the Nobility and the Emperor, through social climbing / raw talent / or by other means they have collected support from the nobility in order to climb the social standings.
As to King George, his Soc got him on the throne and all the perks that came with it.
