We quote the Kli Yakar: "The Midrash (Midrash Tehillim 44:2) says, 'Salvations come to the Jewish nation when they are at the very lowest level, at the nadir. As it states (Tehillim 44:26), נפשינו לעפר שחה כי, when we fall to the earth, לנו עזרתה קומה, that's when Hashem saves us. The explanation is that as long as people aren't at the lowest level, they think they can save themselves from their troubles through their hishtadlus. But when they see that all hishtadlus won’t help them, they place their trust in Hashem, they call out to Him, and Hashem listens. And they rise suddenly from the lowest level up to the highest level. By nature, it isn't understood how they could rise so high and so suddenly..."
The Brisker Rav zt'l would say that he understands how the poor have parnassah. They realize that they can't manage on their own, so they place their trust in Hashem, and Hashem helps them. But how do the wealthy survive? They have their own money, they think they can manage on their own, so how do they have parnassah?" The Brisker Rav concluded that he doesn’t have an answer to this great question.
