(i) Occupation is a job, a person’s role in society wherein a regular activity is carried out for income.
(ii) Certain occupations bring greater economic benefits to the society and the nation at large while certain occupations bring relatively less economic benefits.
(iii) Similarly some occupations require higher level of knowledge and skill while some can be carried out with little or no skill or expertise. Person’s income is proportionate to the economic benefit his occupation brings with it and the land of his knowledge and skill. So the type of occupation determines a person’s income.
