Yes, there was (past tense) a time when I was their employee/servant, and they paid me well and I have no complaints about that. However, the time of employment ceased some time ago and you probably have my farewell letter on file somewhere, so obviously I cannot reasonably count on receiving another paycheck from them in future, so while I may wish them well, and wish I could be more helpful someday because I do believe in their mission, still I am no longer at the office answering phones and processing paperwork, so yes, aren't we all servants in another sort of allegorical sense, but anyway there is no contract of employment at the moment requiring my abject servitude. Slavery was abolished for all races, was it not?
