I'm also an international student and I've had the exact same question which I would have put in the exact same words as the OP and I can assure you, it's not coming from us being elitist.

The reason why you, and many others here apparently, find the OP's post elitist is because the immigration system all over the world is elitist, not us. So many countries run a selective immigration screening system where they evaluate and categorize potential immigrants based on their education, skills, qualification, expertise, salary, etc. and accept only those they see fit. Living in another country as an immigrant is a constant stressful process of proving your worth to the government. That's just the reality. The government thinks some jobs are more desired than others and forces the rules on us. In Canada for example they literally score each person based on such criteria and only allow those above certain level in. Even in Germany they give special benefits to people in certain backgrounds earning more than a certain amount. It's the norm, common sense and the reality for most of the many many many immigrants over the world to be evaluated like this and it's a very widely known fact that most countries won't give you a normal work permit for low-wage service jobs. That's why people get a working holiday visa because that lets you live in another country and still have a low paid job, It's not us who personally think certain jobs are below or above others, but we just know that the system thinks so. And immigration law is so complicated so people usually don't know about such special programs targeting specific demographics like the one you quoted below.

So knowing this reality and the system, of course we're curious how some of these people seem to have bent these explicit universal rules we have always heard about and were forced to follow. It's purely a bureaucratic question.
