Trade skill: (Traveller Rules Page 59)
[T]he character can make a trade check to earn money on a planet that serves that profession. The amount of money that is raised is 100 Credits x the Effect of the check per month.
This means that a very skilled Biochemist (Skill level 3) that is reasonably well trained after years of university studies (Education 9 = skill mod +1) who do standard routine work will earn 500 credits per month
Average Roll: 7
+3 (Skill Level in Trade: Biochemistry)
+1 (Education Modifier)
+2 (Average task modifier)

This means that this biochemist will earn just enough to have social status 2 and save about 100 credits per week as per the ''standard of living table'' on page 2. Still, in Dilettante, page 72, a cleaner is paid 1500 per month ? So this means that a cleaner can live in a better social standing that a well educated biochemist.
Please explain to me how you want this to work?
