Some countries, including Qatar, and many corporations have created the environment which has led to the concept of "me incorporated" meaning you have a set of skills available for hire and when they don't need you anymore for whatever reason you are gone. Your responsibility is to dedicate your skills to meet their objectives while respecting their rules and culture in return for compensation. It is as simple as that. One hopes that once your basic needs are satisfied that you are able to give something back, not to the country or corporation, but those less fortunate than yourselves wherever they may be.
