In the path of the Litvak yeshivot, you do not find an emphasis on what you would call secular learning. And that is for good reason. Since thee is a sin of "bitul Torah",[which is greatly emphasized in the chazal [sages]. ["bitul Torah" means not learning Torah when one can.]
They do see that learning a secular subject as a means to make a living is OK, but it is better to trust in God.
There is also an approach where wives of very serious learners decide to help with making money along with the kollel check.
This is all very admirable. It is good and proper to learn Torah with self sacrifice.
The only place where I differ is that some subjects I believe are not secular at all but rather God's wisdom as revealed in the work of Creation.[Physics, Chemistry, etc. The natural sciences.]
Incidentally the best Litvak yeshivot I know about are Ponovitch and the places that were started by former students of Ponovitch.
