Economan has been infected by the free enterprise bug. He sets up a firm on extraterrestrial affairs. The rent of the building is $7,000, the cost of the two secretaries is $44,000, and the cost of electricity and gas comes to $8,000. There’s a great demand for his information, and his total revenue amounts to $140,000. By working in the firm, though, Economan forfeits the $80,000 he could earn by working for the Friendly Space Agency and the $2,000 he could have earned as interest had he saved his funds instead of putting them in this business.
