You pay a lot for commercial craft beer in America, whether it's a big beer or not, so I think given that people tend to lean toward buying the stuff you sip over session ales. What you drink the most affects your tastes and preferences, and that affects trends on a large scale.
I didn't drink many small craft beers until I started homebrewing. I still don't often buy craft beers under 5% unless I have a very high expectation of quality (I did buy Boulevard's Pop-Up Session IPA last week and was impressed). I'm more likely to make a 4% beer than to buy one.
