From helpless slave to beloved son to aspiring merchant to prodigal heir, Citizen of the Galaxy shows the inner and outer growth of a young man in a far-flung Galactic culture. From the moment he is bought and freed by the beggar Baslim (who is far more than he seems), young Toby learns the values of family, self-reliance, discipline, and self-knowledge. Galactic in its scope and personal in its depth, Citizen of the Galaxy is a well-crafted coming of age story set against a galaxy of contrasts. In a distant galaxy, the atrocity of slavery was alive and well, and young Thorby was just another orphaned boy sold at auction. But his new owner, Baslim, is not the disabled beggar he appears to be: adopting Thorby as his son, he fights relentlessly as an abolitionist spy. When the authorities close in on Baslim, Thorby must ride with the Free Traders -- a league of merchant princes -- throughout the many worlds of a hostile galaxy, finding the courage to live by his wits and fight his way from society's lowest rung. But Thorby's destiny will be forever changed when he discovers the truth about his own identity. - Back cover.

Also, Citizen of the Galaxy and Double Star are really good reads in the same sort of vein of political-minded science fiction.

That's the set I remember most at least. "Have Spacesuit Will Travel" has some good stuff on getting where you want to be in life.
