With everyone in a community making equal salaries:
Ambition would be driven by a more honorable result than monetary gain. The job should be its own reward. It would prevent those from rising to the top whose primary motive is greed instead of a genuine will to help others.
The individuals in the community would all have more comparable financial problems. Therefore, they would all be working towards comparable financial solutions.
Money can equate to freedom. Shouldn’t we all possess the same amount of freedom?
In general, it promotes equality in more of a sense than just finance. Equality leads to unification. [equality vs. class distinction]
Since the quantity of money is finite, the more money a person or group has, the less everyone else has.
