ELI5: Why is Switzerland so rich compared to other European nations?

I've read that it used to be an extremely poor country. What changed?

Imagine Europe is a playground. You know how sometimes a friend might share their snacks with you from their lunch? Or people who simply get along might trade their lunches so both people will have something they like more? Well there are also bullies who might fight and steal lunch money from people they don't like. Well if you stay friends with everyone you can and you don't get into fights with the bullies you will eventually end up with more snacks from your friends, more lunches that you like, and you also won't ever have your lunch money stolen.    

Now that you have all this extra food you could sell that. You can also let people know that if they share a little with you you will hold on to their lunches/lunch money so that it will be safe. Lastly since you get along with everyone teachers don't check your pockets so you could even hold on to the money the bullies steal for a small cut. If people forget you are holding the stuff at the end of the day you get to keep it too!
