It serves to define our conception of economic justice, and therewith the lines on which we should be guided in the adjustment of taxation and the reorganization of industry. I may illustrate its bearing by taking a couple of cases.

The answer in the single case is clear, but it may be said that my good fortune in this case may be balanced by ill luck
