What is to be the limit of poverty or of wealth?

"The form of law which I propose would be as follows: In a state which is desirous of being saved from the greatest of all plagues -- not faction, but rather distraction -- there should exist among the citizens neither extreme poverty nor, again, excessive wealth, for both are productive of great evil . . . Now the legislator should determine what is to be the limit of poverty or of wealth." ~ Plato

Proutist Universal says, every citizen must be guaranteed the constitutional right to adequate purchasing power. If it is denied, then he/she must have the right to sue his/her government. And also, there must be a ceiling on the accumulation of wealth any one person can accumulate, because excessive accumulation by one person of finite natural resources means the denial of those resources to thousands or millions of others. Let each person be content with basic necessities for their life and their work.
