You should be glad by getting a buck per click. There are big percentage of Adsense publishers getting couple of cents per click.
It's normal, don't cost too much time on what's wrong with Google, promote your websites keyword ranking and get more traffic, you'll get much money.
The average CPC is not the exact CPC. It already explain on google term? Plus, publisher will only earn 60%, mistake me if I'm wrong.
Well - let me ask you something... Did you create your own blog with the sole intention of making money from having highly paid keywords? If the answer is yes, then you need to work on writing content - and building traffic so that you can earn more money. Your pay rate is low because your traffic isn't up there - you wouldn't want to pay $6 per click if the site's traffic didn't convert would you?
