Yes that is why I suggested the interest as being better than reducing author rewards because not many users know about it or feel the difference so it would be easier to sell that option to the community. Steemit stake obviously being the most preferable way of funding the worker proposals of course. We need to be careful of adding additional inflation so as not to devalue Steem too much, but since inflation reduces 1% per year, maybe 0.5% can be added to the worker proposal pool, that way inflation effectively only decreases 0.5% per year.
