"average steward"
Of all the stewards in the Traveller Universe, most will be skill-1.
So most of the stewards that you meet on a starship will be skill-1.
Thank you for the explanation. This explains why I didn't understand what was being said at first. I was thinking the comments were something based on the rules and not personal judgement/logic - which from an early age people always commented that I didn't think like the average person. "That's Cosmic logic." was something often said. I substituted Cosmic for my RL first name.
My comments are not intended to be adversarial, people have different opinions and one persons logic may not match with anothers because the world is not black and white. I believe multiple YTU's can all follow the OTU and still be quite different.
due to attrition
On a typical passenger ship, Steward is one of the lowest paying jobs and one of the easiest skills to learn (there are many more people who can serve a meal than there are people who can fly a starship). So a merchant character is likely to start out as a steward for his first term, but as soon as he has two useful skills (say Steward-1 and Engineer-1), he is more likely to transfer to a higher paying Engineer job than choose to continue working as a Steward. So most of the Stewards you meet, are likely first term (18-21 years old) and studying at night to get a better job.
"Attrition" means that most stewards will move on to do something else so that multi-term stewards with Steward-2+ will be rare.
I can see what your getting at, but I don't universally agree.
My first reason is how does this person who starts out as a steward get the training to become a Engineer? If they had the intellect, desire, and/or resources, why start as a steward?
Next, when did employees start dictating to employers "I want to be an engineer instead of a steward". I know lots of skilled tech people from before the tech and economy downturn that had to take jobs they were not trained for in sales and food services. The opposite, I believe, of what is being suggested.

I'm still a little confused as to the purpose of the post. Was it to highlight what was perceived as a problem with the rules based mechanic of perhaps needing a level 2 steward?
First, using the logic, wouldn't multiple merchant crew members have moved up to Engineer and Pilot by being stewards first. Why can't a crew with "secondary" skill as stewards be performing multiple functions?
Second, using the rules, wouldn't all (unless they had another career first) merchant career characters have at least steward 0? Why can't all the crew pitch in and help out with stewarding duties? The Pilot keeping a passenger entertained with a game of chess. The engineer serving up some hooch he made.
