Mission? Loyalty? Company values? Which would do you live in? You are speaking as if the companies are doing a favor to the employees by giving them a job and the employees are at the mercy of these companies.

Being employed with a company is a business transaction, where one party sells their time and skills in exchange for money.

Aren't employees disposable anyway? When the company runs low on cash, they are not going to hesitate to fire you to restore the financial health of itself.

Companies are motivated by money. It is in my interest to be motivated by money too. Companies are not loyal to employees. It is foolish to expect employees to be loyal to companies.
