The greedy 1% that owns most of the world's wealth are the whales you speak of, but most people hate them with a passion.
There is no mechanism that would preserve people's liberty and produce a different wealth distribution.
QFT.
No mechanism, perhaps, but there are people. When the extreme wealth concentrators develop their relationships with other people, their hoards tend to dissipate. This can be done well, in a generous, healthy and growth-positive dynamic, or pathologically, via thievery or guilt-trips, &c, creating unhealthy dependence relationships.
What is the source of this hate?
Jealousy is just another face of greed.
There is another reason to contend against the concentration of wealth: The suffering created by poverty. The injustice of extreme wealth divergence is plain, and for many of us, quite painful. When I am in pain, I tend to lash out against the perceived cause. When the pain reflex, the noble and just cause, and the venial jealousy are all aligned to a single focus, it is a powerful force, and difficult to effectively counter. The solution is to factor the problem into its facets, and deal with them each individually on their own terms.
