So here's what I do anyways:
1) Juice up and recruit.
2) Send recruits to "elementary school" where they're taught Infiltration skills.
3) Use those infiltration skills to repeatedly sneak into cosmetics labs and juice up to, say, 100 juice each.
4) Once you figure they're ready to graduate elementary, give them "high school" till they hit new maxes.
5) Now use improved infiltration skills to free prisoners until they've all got really decent juice, say 500 each. Now they've graduated high school.
6) Send them to college... Get them up to level with your super juicy boss in skill if possible, including more than just the Infiltration skills.
Repeat the process for more trainees, and put them into service making clothing or raiding or writing or whatever. Let your bosses teach.
My biggest problem has been getting enough fighting skills built up to be worth teaching. I intend to cover that by training those skills with a less important squad and then getting them to teach the skills to my leader, who can then teach those skills to everybody who doesn't have them.
My leader has 17 teaching. Don't want to get him into trouble.
Also thinking of putting a programmer, a priest, a lawyer/judge, a lab tech, etc into education courses to teach to my leader. Anyone who's got significantly more skill than my leader in something ought to get teaching skill to add said skill to the pool. That will be one incredible teacher in the end... If all my mad schemes come true...
EDIT: May I also add that liberals can learn from a teacher while they're busy churning out expensive suits... Probably also while taking education (for example) courses in school.
