The world can end up better off in certain cases of one person controlling huge amounts of resources rather than collectively deciding what to do with them.

But if you think that's always going to be the case, why bother having democracies then? We can return to the tradition of noblesse oblige and let kings and lords take all the products of everyone else's labor and just hope that they'll feel sufficiently obligated to be kind and charitable to the rest of us. There are plenty of people who believe this, so you won't be alone, and I'm sure others will argue we're better off now that the men being rewarded by being allowed to own everything got there by being good at product design and regulatory capture rather than past centuries when they were good at raising armies and taking land from other people.
