Man offers seven children for sale
Its a sorry situation but here is my take on the whole episode.
The man did not get education past high school. May or may not be his fault.
Could not get a job; what was he expecting after only high school education, the competition is fierce. Again something which may or may not be in his control.
Decides to get married. This was definately under his control, he should have waited until he had a proper job to support family.
Decides to have 7 children. Here he was totally out of control, he should have considered his financial situation.
And now he is asking the officials to arrange a job for him or he will sell his children. Either its a good investment plan or a blackmail.
