> In return they got free labor

For one, it sounds like you might be placing undo value on your grunt labor. But more importantly, it sounds like you don't see that you made out on the deal, and they got the short stick of your grunt labor.

> We have no basis for discussion so this will be the end of my replies,

It would have been more honest of you to admit you're annoyed at dissent, and don't wish to discuss further, but instead, passive-aggressiveness.

Be well.

Please don't selectively quote, the full sentence is "In return they got free labor and payed their debts forward to the people who originally mentored them."
