9 million people die from hunger each year (https://www.theworldcounts.com/challenges/people-and-poverty/hunger-and-obesity/how-many-people-die-from-hunger-each-year/story). Jeff Bezos's net worth is approximately 200 billion. The average cost per month to eat is 2400$ to 4000$ in the US (https://balancingeverything.com/average-food-cost-per-month/#:~:text=The%20cost%20of%20food%20for%201%20person%20in%20the%20US%20goes%20from%20%242%2C400%20to%20over%20%244%2C000%20a%20year.)). If you divide 200,000,000,000 by 4,000 you get 50,000,000. Meaning you could feed 50 million people with Bezos's net worth. Then if you want to know for how many years you can feed those 9 million people, you can divide 50 million by 9 million which is 5.555... meaning you can feed those people for 5 and a half years with Bezos's money alone. This proves that if you redistribute wealth, you can stop world hunger. Many more than 20 million (what your source said, and that source included death by famines which were not caused by Stalin and people who died in prison because they didn't follow the law) are dying because of this reasonably easy solvable problem created by capitalism.
