+	Master, while many of your slaves work hard to earn ¤ each week, some succeed more than others.  As a trader in slaves, you may appretiate the opportunity that comes when a particularly valuable slave is a low earner.  Or perhaps you just want the chance to tweak these problem slaves and train them to be better.  The choice is yours.
