Think about the implications if the world worked as your question implies that it "should": A $15 share of stock would return you (at least) $15 after 3 months, plus another $15 after 6 months, plus another after 9 and 12 months. This would have returned to you $60 over the year that you owned it (plus you still own the share). Only then would the stock be worth buying? Anything less than $60 would be too little to be worth bothering about for $15?
Such a thing would indeed be worth buying, but you won't find golden-egg laying stocks like that on the stock market. Why? Because other people would outbid your measly $15 in order to get this $60-a-year producing stock (in fact, they would bid many hundreds of dollars). Since other people bid more, you can't find such a deal available.
(Of course, there are the points others have brought up: the earnings per share are yearly, not quarterly, unless otherwise noted. The earnings may not be sent to you at all, or only a small part, but you would gain much of their value because the company should be worth about that much more by keeping the earnings.)
