Switzerland's economy is adorably small. It is approximately 3x the size of LA County, and in there are cheese makers, watch makers, ski chalets, etc.

"inspiring great affection; delightful; charming"

This seems adorable to me.

Adorable is used to belittle things -- it's even a meme:

“That’s Cute” (otherwise known as “That’s Adorable”) is a sarcastic expression used to patronize or dismiss someone’s self-complacency or boastful statement, similar to the phrase “bitch, please.” It is typically used to juxtapose the capabilities or accomplishments of two comparable subjects

I think it's meant as a diminutive. Also, economies have natural sizes that are not bound to geography; it's rather easy to compare them on any number of characteristics.
