The foundational idea behind money seems to be:

Be of “value” to others, by involving in selling something. Earn “value” in return, by earning money.

Some problems are:

• This “value” earned, namely money, is often unequally distributed.

• Value to other people isn’t the only measure of value.
  For eg, consider Scientific Discoveries which improve Knowledge but don’t translate into direct value for other people.

• People have often unfairly unequal opportunities to participate in value creation.

Is there a simple “solution” to economic inequality people are missing?

To study: Countries with less economic inequality, like Norway and Finland.

Institutions can make it easier for people to participate in value creation?
