Switzerland is a country with one of the highest standards of living in the world. How did a landlocked country with almost no natural resources become so wealthy? Is it purely due not being involved in any wars during the 20th century? And what is true of the Swiss "stealing" gold after WW2 by not returning it to the (family of) rightful owners?
There is always more to be said on a topic, but you may be interested in an answer I wrote eight months ago on why Switzerland is rich, which responds to the first part of your question.
