Why People Send thier Children to Cadet College?

This is the question in my mind that I want to ask the people who send their Childs to Cadet Collegs.The the answer that I think is that they think my studying in Cadet College the future of their Childs would be better. And most o the Parents send them their with the attention that they may join Pakistan Forces. But the thing is that they should realize that by joining Cadet College it is not confirm that their child would join Forces.And we an also see that the ratio of selection from Cadet College is not too high. See Pakistan Steel Cadet College the average per year Selection in Forces is less then 6 per year.
