Drop in standards for Singapore Airlines

I spoke to a stewardess who has worked in Singapore Airlines for nearly 40 years and is due for retirement. She flew for many years to wear a purple uniform and was grounded to take up a lounge position during the later years.

Me: Has a quality of service of Singapore Airlines dropped over the years?
She: Definitely.
Me; What is the reason?
She: The younger cabin crew has a short term goal, to fly for a few years, visit places around the world, and then move to another career. They do not see a long term career in the airline.
Me: Is this phenomena affecting all airlines, or does Singapore Airlines fare worse than other airlines?
She: I think it affects Singapore Airlines more.
Me: Has the attitude of the workers changed over the years, compared to the old days?
She: Yes, younger workers are less committed.
Me: Could it be due to the change in the company policy also? In the old days, the company invest in the workers and give them prospect for a long term career. Today, the company is more short term minded. This attitude must affect the workers who also respond in a similar fashion.
She (after reflecting for a while): I think you are right. I did not think about it from this angle before.
