total income is divided between different groups or individuals.

each extra worker adds less to output than the previous extra worker added.

The ‘invisible hand’ is the assertion that…
the individual pursuit of self-interest within free markets may allocate resources efficiently from society’s viewpoint.
In a mixed economy the government and private sector..
