[单项选择] Young men and women today are finding it more and more necessary to protest against what is known as the "Establishment": that is, the people who wield (掌握)power in our society.

In particular, the Establishment should adopt different attitudes to work and the re wards it brings. Today’’s young people are ambitious. Many are equipped with a good education and are understandably impatient to succeed as quickly as possible. They want to be able to have their share of the good things in life while they are still young enough to enjoy them.

As the Establishment controls the purse-strings, its views are inevitably imposed on society. Employers pay the
