I think the sequence of events you're proposing is implausible, on the order of likelihood of a zombie apocalypse or the apes rising up to overthrow mankind.

"If we decide that billionaires represent a policy failure that has allowed a few to concentrate wealth and power and society collectively wrests some of that back from those with such a disproportionate power and wealth, then that means eventually 'they' will come after my inconsequentially meager possessions."

I don't see it.
