I suggest watching the (non free) documentary called 'Google and the World brain'. It makes clear that the aim of Google has never been to make money and it was, in fact, initially aimed at creating the world's largest synthetic 'brain' - using our internet input as a learning aid.
Keeping in mind then that the entire premise of Google is a facade - it should be easier to understand that Google is more of a false front for a variety of research projects and social engineering agendas than it is a valid service offered in an honest way.
