Some years ago Edicted proposed savings accounts with nominal interest to compensate whales with ROI to replace curation rewards. HBD savings accounts are now implemented with 20% interest rates. However, whales have not eschewed curation rewards. They are simply double dipping, as there is no mechanism that prevents them from doing so. Since they control governance, as the only metric by which political control is availed is stake, and whales have the majority of stake on Hive, they have not sought to cut themselves off from curation reward income.
The problem is greed, pure and simple.
More like control.
They already have all the power and hive enough to control the pool for years to come.
It's not greed, it's desire for power.
Much worse, imo.
