Second, I'm not saying that we should treat economic inequality as something that's static or immutable any more than any other natural force. I'm saying that we have to recognize that natural forces dictate behavior and economics, and that you can't change natural forces by decree alone (e.g., passing a law that says "everyone now must share"). We have to really appreciate and understand the processes and motivations that drive the behaviors if we want to address them in a meaningful way.
We have to be honest about how changeable certain things are. For example, we have not, as yet, found a way to control the weather explicitly, but we have coping mechanisms like air conditioning that mitigate some of the negative effects. This didn't happen by saying "It shall always be 74 degrees indoors at all times" and then laying down stringent ideological enforcement to ensure that everyone accepted and believed that it was always 74 degrees. It happened by experimentation, tinkering, and respect for the constraints of the reality that allowed us to discover a non-ideal but workable solution that mostly handled the problem of uncomfortable heat.
There is not necessarily any reason to believe that the current mix of inequality conditions are particularly cruel or unfavorable. American free-market enterprise may not be perfect, and I'm not saying that there are no systemic issues or that things aren't worsening, but our economic system is historically workable and reasonably well-tuned. It has proven much better than many competing systems. We have to be honest about where we are and what's possible.
We can't simply change "the rules" and expect a good outcome, as the comment I replied to implied. There is no magic wand and no overnight perfection.
