Do Dutch people like foreigners?
In my experience yes, but remember that no one likes a jerk. I've been to Nederlands twice and a lot of other countries in Europe and almost universally, the people were friendly, polite, and welcoming. But I also saw a lot of tourists who were rude, self-important, self-righteous and impatient. Different countries generally had different levels of tolerance for that kind of behavior and some of them were more open and direct about not having any patience for those kind of people.
The Dutch tourist branche depends on foreign visitors for a great deal;
The Dutch agricultural business, depends on foreign workers also;
The Dutch medical care, builds on foreign professionals too at the moment.
Our universities are promoting their specialisms to foreign students all over the world generating great response.
Our cities welcome international firms and entrepreneurs (acting inside the law) with open arms...
