Hi write or wrong.
You bring up interesting components to this problem.
There can be numerous solutions or none at all.
The problems I mentioned, in my opinion, are deeply systemic. They dominate the outlook of the community, our yeshivas, the families, and youngsters themselves.
Attitudes are very difficult to change. Teachers, alone cannot control the curriculum or even totally influence that yeshivas have adequate resources to teach with.
The measuring stick we use to define who is smarter and more successful and even more Jewish, is solely dependent on a curriculum of learning which favor people who are heavily left brain hemisphere oriented (logical, sequential thinking).
And what about those who are more balanced or heavily right brain hemisphere oriented (spatial, intuitive, creative)? They are left out of opportunities to develop, or, at best, told such endeavors are shtuss. They are neglected, looked down upon, and discouraged.
There are no immediate answers. We have a lot on our plate now: loshon hora, internet, derech deviation issues, finances for yeshivas, a “shiddich crises”..etc.
We are a smart people. Our forebears were able to be frum and successful in a variety of endeavors when the outside society made it difficult for them to be Jews. Here, in America, we have freedom to look at our institutions and change them.
My only real solution that is workable is that I, as an individual, and teacher, can try to be encouraging and offer inspiration to hold them over until they are adults and can find the educational opportunities and support in career endeavors, as long as we dont lose them before they emotionally drop out.
