Life should not be as hard as it is. It is hard, and it is not painless, but it's harder and more painful than it must be. We have billionaires siphoning money from the masses (either directly, or indirectly via government action) that are already struggling. Redistributing even half of their net worth would be a life-changing amount for the average person, and could put wind in the sails of many charitable/educational/scientific/medical causes.
There is no reason why the current situation should be allowed to continue, and many reasons why it should not. Obviously it's a hard practical problem to crack (given that a naive approach to redistribution of this kind would be met with a great pushback and implode various systems that we depend on), but unless we do something effective, we'll keep ruining the planet while trampling the poor at the same time.
