This is really something worth to think about. Assuming people will get 50% of what they are voting, I am sure the motivation for upvoting others is much greater. However, when I look at the perspective of authors, it is less lucrative as the most work effort is from them.

When you talk about equal distribution of wealth, this means that the authors will need to see a bigger picture whereby there will be more people that willing to support their work rather than complaining about the earning had reduced by around 33%. So in overall, it may become beneficial for the authors as people will be driven to support better quality works.

My 2 cents after reading :)
