Mat 20:14 Take yours and go your way: I will give to this last, even as to you.
Mat 20:15 Is it not lawful for me to do what I want with mine own? Is your eye evil because I am good?

Christ here sets out the principles of private property. First, you are entitled to the compensation for your efforts, but only to what you have agreed to. Second, you are entitled to do with your property whatever you want. Just like other people cannot say what is "fair" for you, other people cannot say what you should do with what you have earned.

This idea is very profound. It says that there is not simple standard for economic value. Every person is free to say what their effort is worth. Every person is free to say what they find valuable.

How other people see us is NOT the measure for what is fair or good. Everyone has their own perspective.

(Note: The phrase, "Is your eye evil" sounds odd because of the standard mistranslation of poneros. which though always translated as "evil" means "burdened" or "worthless." A better translation might be "Is your eye burdened" or "Is your eye worthless." "Good" is also from the standard term, agatha.)
