Broadly there are two types of income--earned income and unearned income. Earned income is something for something--or return for goods provided or service rendered. Unearned income is something for nothing--an income derived from some monopoly, privilege, sinecure or form of property ownership. Property in persons or things has been a characteristic feature of all civilizations. Property owners, receiving rents, interest, dividends, in proportion to the amount of property which they own are not called upon to make equivalent return in exchange for their property--based income. This personal parasitism of property owners is aggravated by provisions of property law under which the owners of property can give, sell or bequeath these sources of unearned income to family members, friends, associates. Eventually, unearned income, handed on through generations, creates a class or even a caste of citizens who live without rendering an equivalent of services, on the labor of their fellows, adding a significant amount to the total of overhead costs. Wealth ownership, the exercise of power, living in luxury on unearned income, add to overhead costs, but are accepted as respectable in civilized communities. Another and far less respectable form of social parasitism is the manipulation of social forces in a way that will bring the operator more than a fair share of social income with no equivalent in service. Such is "politics" or "politicising." "Politics" as a source of livelihood takes many forms, some less legitimate than others. The most usual source of office-holding is the humble work of the clerk, handyman or messenger, responsible for carrying out the nagging routine of government. Beyond this common labor of public service are public servants skilled in their several professions. Beyond and above them are department heads and still higher are the appointed or elected officials responsible for the success or failure of a given public policy. Who are the occupants of town, city, state, and national positions of authority and responsibility? Preferably they are elected or appointed because of their popularity or are the successful product of civil service examinations. At worst they are appointed as a return for favors or else because they are relatives or friends of successful politicians or their backers.
