When a government passes a law granting citizens tax credits if they use public transportation on a regular basis, it is using the incentive technique.
Incentive refers to positive rewards provided to certain individuals in order to encourage them to do a certain activity.
Granting tax credits for citizens who use public transportation would be useful for the government in their attempt to solve the issue pertaining to traffics on busy roads while making the citizens feel rewarded for behaving well.
America went through a tough time during this age. The government was very corrupt and authority could easily be bribed. This is why court cases against these things could not easily be won, because of the corruption.
