aries,
What system? The yeshiva system? The yeshiva boys I know practice all of the things you’ve mentioned to a higher degree than the boys who are not in yeshiva. The Torah itself teaches these things, and in my experience, serious talmidim practice what they learn.
Of course, in our generation there’s less respect for parents and elders than in previous generations, and even b’nei Torah are nebach affected, but they’re still better than their counterparts who dropped out!
