Wouldn't people that click on the ad links of the spam sites also click on the ad links of the non-spam sites?
So what's Google's benefit to annoy everybody with non-quality search results? I'd guess, the SEO is currently just too good.

I agree with your hunch; however, bounce rate is a relatively bad thing. If, using analytics, you see that most users navigate away from your page within 30 seconds, you probably don't have engaging content. How is that different than the user clicking on an AdSense ad because the content on a spam site isn't connecting emotionally or intellectually with the users? If anything, Google should be giving a negative score to sites that have a huge percentage of their users that actually click on ads to continue the search for what they were originally looking for... though that is basically the opposite of their business model, to have users click on ads.
