Oliver v. Halstead, 86 S.E. Rep 2nd 85e9 (1955):
"There is a clear distinction between `profit' and `wages', or a compensation for labor. Compensation for labor (wages) cannot be regarded as profit within the meaning of the law. The word `profit', as ordinarily used, means the gain made upon any business or investment -- a different thing altogether from the mere compensation for labor."
Lucas v. Earl, 281 U.S. 111 (1930):
"The claim that salaries, wages, and compensation for personal services are to be taxed as an entirety and therefore must be returned by the individual who has performed the services which produce the gain is without support... it is not salaries, wages, or compensation for personal services that are to be included in gains, profits, and income derived from salaries, wages, or compensation for personal services."
Conner v. U.S., 303 F Supp. 1187 (1969):
"... whatever may constitute income, therefore, must have the essental feature of gain to the recipient. This was true when the 16th Amendment became effective, it was true at the time of Eisner v. Macomber Supra, it was true under Section 22(a) of the Internal Revenue Code of 1938, and it is likewise true under Section 61(a) of the I.R.S. Code of 1954. If there is not gain, there is not income ... Congress has taxed income not compensation."
Edwards (vs) Keith, 231 F110, 113 (1916):
"The phraseology of form 1040 is somewhat obscure .... But it matters little what it does mean; the statute and the statute alone determines what is income to be taxed. It taxes only income "derived" from many different sources; one does not "derive income" by rendering services and charging for them... IRS cannot enlarge the scope of the statute."
Lauderdale Cemetary Assoc. v. Mathews, 345 PA 239; 47 A. 2d 277, 280 (1946):
"... reasonable compensation for labor or services rendered is not profit."
