'Higher the qualification more the income ' - Shall we agree ?

When we think we have to earn the first question that comes to us is- How to earn? Next we start calculating what skill does an individual have which s/he may utilise to start earning .Ultimately one counts on one’s educational qualification and tries to generate income from that according to their own capability.

Now the point comes – What type of educational qualification is needed to earn ? Does it require only the basics of literacy prgramme that removes illiteracy or it requires more that includes primary education or we can include even more that is minimum graduation from any university .Common logic says - higher the qualification more the income .But to my mind it is not necessarily true. An individual might have a greater income with simple Primary education if s/he has the ability to organise and execute one’s special skill in any particular field. We must not forget the Non-formal education which enables a large section of society to earn their livelihood with simple primary educational qualification.
