In 1955 the society told everyone don’t do shit to change anything. It was a time of restraint and repression.
In 2005 society was in a revolutionary mode and told everyone to question and disrupt everything.
So to tell people to challenge what was allowed in 1955 actulally was a good and vital thing to change society. In 2005 challenging what was allowed was mostly done for personal gain, exploiting the system.
