Quizplus · Accepted Answer

The size of the federal government has increased substantially, and it has involved itself in a range of issues, including social welfare, environmental regulations, and consumer protection, among others. As a result, many interest groups have emerged to represent the diverse interests affected by these policies. This has contributed to the dramatic increase in the number of interest groups over the past 50 years.
