I think your reason is valid Jack. My experience was that many parents at the hagwon I worked at did indeed want younger teachers for their children. But, as you say, that would not apply to adults -at leaast not to the same extent.

There is a feeling that younger americans are more in tune with the business world - this, of course, is a generalization that would be hard to back with facts- because it isn't true in every or , I suspect, most cases.

I have noticed a difference between koreans and Chinese regarding age. Both say it is impoortant to have the wisdom of age- only the Chinese actually mean it.
