AdSense is crap - Help!

Does anyone know how to make AdSense pay better?

My last 12,000 page impressions have produced just 46 clicks.

My earnings are a pathetic $7.10 or a cost per thousand impressions of $0.58.

I knew AdSense wasn't going to make me rich but, well, this is just risible.

Does anyone know how to

i) increase the number of clicks you receive per page impression and
ii) increase the CPM rate?

Or, are there any better Ad networks to use?
