There are those who think that the mitzva of supporting Torah is not incumbent on them since they have other financial burdens. If they would analyze their expenses, they would realize that there are many things that are not really essential, whereas supporting the Torah for which Hashem descended from His Heavenly Throne to this world to give us His Torah is beyond their means.
This is like a person who has a hotel with fancy rooms for wealthy guests, simpler rooms for those who are just well off, and beds in the corridor he rents to poor guests. Most hotel owners will check the expensive rooms personally on a regular basis lest there be anything lacking since that is his main income, whereas he will rarely pay attention to the beds in the hall. If he would do the reverse, and ignore the expensive rooms looking after the beds in the hall carefully, he would be considered a fool. The correlation is obvious, service of Hashem is what we are here for, and that is the source of our livelihood in this world and the next, whereas our physical needs are secondary. A person who focuses on his physical needs and neglects his eternal existence shows himself to be a fool. This is what the verse refers to when it describes ‘I saw servants riding on horses and ministers walking like servants on foot’. Such a person will see the catastrophic results of his foolishness in the world of reward, as our Sages said, ‘Whoever makes Hashem’s Torah his focus in this world will be made important in the ext world’.
Fortunate is the person who takes this to heart in this world, and he will reap his rewards in the world to come.
