Inequality Is Required In Order To Measure Wealth

How, exactly, does one measure "wealth" within a system of equality?

If 10 people each possess $100,000,000, who of the 10 people is "wealthy"?

Doesn't quite work, does it?

Without differing levels of income which, once measured, can then be compared to each other, it is impossible for "wealth" to exist.  Essentially, the concept of wealth can only exist in so far as inequality exists between those being compared to each other.

Is it not safe to conclude that wealth can only exist so long as poverty exists?

Wealth is a measurement of relativity.  Wealth requires poverty in order to be defined as such.  The money-market system requires inequality in order to measure wealth of any kind.  Therefor, as human beings, we participate in and knowingly support a system that creates inequality as a necessary component of "creating wealth" (or the illusion of wealth).
