Question

Hello Rabbi,
I’d be glad if you could share your thoughts with me on the following issue. In the end, I think it’s a kind of subsection of the question of “the righteous who suffers,” and I haven’t really found an explanation that satisfies me—not only intellectually, but emotionally as well.
It’s hard for me to understand how a person whose lot in life has not been good is supposed to feel as a believer. Whether we’re really talking about someone whose lot has not been good, like hungry children in Africa, or someone who received a poor education, or someone who has one disorder or another, or just someone for whom “things didn’t work out.” The feeling of “unfairness” cries out. The world is not “fair” to the individual, at least. Bad things happen to good people, certain people are naturally more inclined to be happy than others, etc.
Why wasn’t everyone given an equal opportunity to be satisfied with their situation? Why weren’t they given equal potential to do good, to succeed to the same degree? After all, in the end the main test in the world—at least from what I can understand—is what a person does with the choice given to him—for good or for bad, at any given moment. If so, why wasn’t everyone given the same starting point?
(And likewise, what place is there to give thanks for what one does have, when there are others who don’t have any of that? It sounds absurd to me to give thanks for things given to you while others suffer and did not merit to receive those same things—it doesn’t seem to me that there is any moral value in that, but rather the opposite.)
Although one thought did occur to me: perhaps this is necessary, since a person was given free choice, and therefore he can also use it for evil, and so it may be that he harms others as well. Even so, the person to whom some wrong was done—what is he guilty of, and how is he supposed to relate to this on the scale of justice in which he believes the world operates? In addition, not all the “unfairness” that exists in the world stems from the evil of other people. People are born into certain conditions that they may never be able to escape, regardless of other people’s evil, and with certain genetics that limit them within certain boundaries.
In short, free choice was given, as I understand it, to do good or evil, and if so, it is very hard for me emotionally, at least, to understand why not every person is granted an equal starting point, from which onward he would be judged. How is a person who did not receive such conditions supposed to encourage himself, and to see even such a thing as something of value, and that even though he was not granted certain things like others were, it is still “worth it,” and has some kind of benefit?

Thank you very much, and have a pleasant rest of the week.
