Repeated radical cashectomies, until wealth inequity is decidedly pro-democracy.

Alas, from the little I've read about both reform (new legislation) and revolution (new constitution), the wealthy elite squirm thru, never truly losing their power advantage. (Probably because any new agenda still needs to be capitalized.)

eg The Nordic model worked pretty well for a while. But weren't durable enough. Allowing the Wormtongues to undermine it all, one millimeter at a time. Opening the door for another cycle of revanchism.
