I find this refrain tiresome. I grew up in a US suburb and had similar experiences to what you describe outside the US. I mean, yes, there are some suburbs in America that are husks of their former selves due to economics, etc. But I grew up in a small midwestern suburb of a failing city. I had the following:
1. Would regularly walk or ride my bike to the store with my friends to get things at the age of 7+.
2. A vibrant art scene.
3. A plethora of science and learning opportunities including a branch of a well-known University.
4. A walkable downtown with mom and pop stores.
5. 30 minutes from big events like concerts from our favorite rock bands. 60 minutes from famous sports franchises. 30 minutes from the symphony and art museums.
6. 5 minutes in the other direction was rural farmland where you could learn about agriculture, etc.
