That's very reductive. Famously Switzerland has difficult terrain and many of the large infrastructure projects happen in the alpine region. Some of those projects are quite challenging and require international effort and coordination. GDP per capita being higher is an advantage, but it also makes everything more expensive domestically.

The approach outlined in the article, is also not applied generally to all infrastructure projects. It's specific to transport. It works because the process is sound and long-term oriented and not because Switzerland is small and rich. Perhaps your comment even inverts the causality.
