Current events can affect public policy in the future in several different ways including:
1) Learning from past mistakes- If there is a law or program implemented right now that is not necessarily successful, future public policy makers could avoid implementing that program again.
2) Building on past succcess- If the government implements a public policy that helps the economy or Americans in general, they can continue to build off its success. By examining what made the program successful, policy makers can continue to include those elements of the program to ensure continued success.
