A changed system of employment in the various economic sectors worldwide
( In core countries, people design and develop products for the global market. Tertiary, quaternary, and quinary jobs have increased in the core. • In semiperiphery countries, people often manufacture goods marketed in core countries. Consequently, employment in the secondary sector has increased. Employment in the primary sector has declined. • Periphery countries, such as Bangladesh, Angola, and Papua New Guinea, have large primary sectors and export minerals and resources to core and semi-periphery countries for further processing and consumption. )
