Hear me out before you judge:
The question of Hishtadlus (personal effort vs relying on G-d) is deeply rooted in our sources, the Torah tells us that when Yaakov anticipated a violent meeting with Eysov he divided his time and effort between preparing a bribe, praying to G-d to save him and preparing for war (Rashi on Gen 32).
"התקין עצמו לשלשה דברים: לדורון לתפלה ולמלחמה.
.(לדורון - "ותעבור המנחה על פניו" (פסוק כא
.(לתפלה - "אלהי אבי אברהם" (פסוק י
.(למלחמה - "והיה המחנה הנשאר לפליטה" (פסוק ח
However, it appears that eventually, the Jewish tradition took a different turn - in the face of all worldly problems it focused exclusively on worshiping G-d and asking for a remedy. We spend about 2 hours daily in a Shul for prayers and twice that time on Shabbos and Yom Tov, but no time for learning first aid or resuscitation or preventing most common diseases or the basics of the economy or maybe the psychology of Shlom Bayt. THere's no obligatory Hishtadlus for prevention of any of the problems we beg for.
Based on Yaakov's example, I would expect the Rabbis to institute mandatory everyday learning of those life-saving subjects for the whole community, in parallel to the prayers.
Why did Hishtadlus and responsibility for our own wellbeing disappear from our Jewish everyday conduct?
