On Profit (Villegas vs. Villegas)

• Profit is a residue, the difference between revenue
  and cost but the simplicity of its definition is deceiving.
  Profit is a reward for assuming possible
  losses through risk and uncertainty. - Dr. Bernardo Villegas, UA&P
  
• Profit is the surplus value produced by a worker
  which is converted into money. - Dr. Edberto Villegas, UP Manila
