"Relative wealth" is crucial because humans inherently need to continuously exchange with the outside world to improve efficiency.

Even if an individual excels in a certain field, if others can produce higher quality results at a lower cost, that person's value will decrease. To enhance "relative wealth," one can approach it from two aspects:

First, widen the scope of communication and transactions, exchanging resources with more individuals in a larger space;

Second, engage in complex and unique endeavors to create core competencies that are difficult to replicate or replace.
