1. Income-generating work is the work produced by an individual by means of the expenditure of his energy and time.
This is a reminder of what is admitted in Chapter 2 about work, with the distinction between work-expenditure (the means) and work-work (the result).
2. Income from work is generically called wage in economics.
Wages, emoluments, wages, attendance fees, tips, wages, and wages are, among other things, Wwge. But fees, fees, freelancers are often revenue as are always the rents received.
3. Only income from work constitutes wages
This definition excludes from wages all interest, profit and capital gain. Only individuals receive wages.
4. The distinction of roles improves economic theorization and organization.
The worker and owner, or member of the enterprise that employs him, is, on the one hand, an employee and, on the other hand, an usher. The assimilation of a social class to an economic role is based on the atavistic idea that the practice of economic exchanges induces irremediably contradictory interests.
