7. In Eretz Yisrael, a paystub is called a tlush (משכורת תלוש). Another translation of תלוש is detached. This is when one receives a set wage, and he relies on that, and he detaches himself from feeling dependent on Hashem. Obviously, we aren’t recommending that people shouldn’t take a job that pays a fixed wage, rather we are encouraging people to remember that no matter what type of parnassah they have, they should turn their eyes to Hashem, for Hashem is the one who gives parnassah.
Rebbe of Sokolov zt'l answered it according to the Chazal (Koheles Rabba 1:13): "Whoever has a hundred wants two hundred." So the wealthy also feel lacking and turn their eyes to Hashem to help them.
We say in the Haggadah, את לעקור בקש לבן הכל, “Lavan wanted to uproot Yaakov Avinu” from Hashem. We can explain that Lavan wanted to give Yaakov a set salary. He said (Bereishis 30:28) ואתנה עלי שכרך נקבה, "Specify your wage, and I will give it." He wanted Yaakov to feel that his parnassah comes from Lavan, not Hashem. Yaakov didn't want that. He wanted a parnassah that would cause him to constantly turn his eyes to Hashem to help him. And indeed, Yaakov trusted in Hashem and had immense success.
