SEO and Google

SEO works for google.
If google can hammer the point that good sites rank higher, that is.

That way google gets better results for a term. This also serves as a self-correcting mechanism. Google is better off getting a lot of good results to choose from, no matter what the motivation behind.

What difference does it make if a good website appears front on google, provides good information to the user, and is optimized. Why discard such a site because it was optmized?
