וַיַּחֲלֹם וְהִנֵּה סֻלָּם מֻצָּב אַרְצָה וְרֹאשׁוֹ מַגִּיעַ הַשָּׁמָיְמָה וְהִנֵּה מַלְאֲכֵי אֱ-לֹ-הִים עֹלִים וְיֹרְדִים בּוֹ "And he dreamt, and behold, a ladder placed on the earth with the top reaching the Heavens, and angels of G-d were ascending and descending on it" (Bereshith, 28:12). The Ba'al Haturim says that the gematria (numerical value) of סולם (Sullam - ladder) is equivalent to the word ממון. Hakham Yosef Hayyim, 'a"h, writes in 'Od Yosef Hai, in the name of his father Hakham Eliyahu Hayyim, 'a"h, an explanation of this pasuq (verse) based on this Ba'al Haturim.
The Sullam which refers to money is מוצב ארצה (on the ground), meaning to say that a person sees his wealth and income based on what he does here in this world. However, וראשו מגיע השמימה (the top reaches Heaven), meaning that, in fact, everything a person receives in this world is really dependent on the will of Hashem.
If He wants the person to earn he will, but if he doesn't he won't, no matter how hard he tries. This is showed by the angels going up and down the ladder. These are the angels responsible for one's income. For some people it is positive and those are the angels going up, whereas for others it is not so positive, and those are the angels descending the ladder.
