Some would argue that is what builds character, and the grit to succeed. Not saying extreme poverty is “good” necessarily. Just that the jury is still out on whether or not humanity as a whole is better without suffering (specifically if it leads to a decline in the human race).
Universal basic income has been suggested and to some extent tested for thousands of years. None of succeeded, but the devil is in the details and perhaps soon the machines will take care of us.
For reference: I came from a poorer background (not extreme, but enough I noticed). I view it as my greatest strength, as it forced me to learn faster, specifically taught me the importance of relationships, community, hard work, determination.
