That is not low CPC for a niche like yours. So try to increase your impressions/traffic, don't worry about CPC!
I absolutely agree with you, low paying country. Why do advertisers pay more if they can publish ads with low cost? Google don't give high price on low competitive market.
CPC depends on your niche (you are in an average one) and at which rate those guys clicking your ads convert to customers (the better the more pay out for you).
