Roy Hudd,
if you read my post well, you'll notice I was making an example of generalisation. Languages BTW are only an aspect of the job. Engineers do their job, just like Cabin Crew do theirs. Aircrafts wouldn't fly with only engineers, or only CC. They need both to make an airline. Now, if someone is not happy with his salary, he has two options
1) Get another job, provided they have the requirements.
2) Negotiate a higher salary.
To disparage others is no use whatsoever.
