Final answer:
Public choice theory assumes that individuals in the public sector are largely motivated by self-interest.
Step-by-step explanation:
Public choice theory assumes that voters, politicians, and other individuals in the public sector are largely motivated by their self-interest. This means that they make decisions and take actions that they believe will benefit themselves.
For example, politicians may support certain policies or take certain actions because they believe it will help them gain more power or get re-elected. Voters may support a candidate or a specific policy because they think it will benefit them financially or in some other way.
