Answer:
The private sector and the public sector cannot be viewed as separate entities because the two of them are closely intertwined.
Step-by-step explanation:
The public sector defines the rules and conditions under which the private sector develops, and the private sector contributes to the finances of the private sector.
For example, a regulatory agency in an economic sector sets the rules of the mining economic sector in a country, and private mining companies abide by these rules in order to develop their business activity. Part of the revenue earned from these business activities are taken as taxes by the public sector, in order to finance the regulatory agency.
Sometimes, the public sector can also consists in public companies that can work together with private firms in common projects.
