Thanks Daniel for sharing the Baha'i concept of work as worship... I believe there may be a similar principle in the Bhagavad Gita where Krishna tells Arjuna that he must perform his duty as an act of dedication.
Any way... I believe we also have a specific principle that can reduce the extremes of wealth and poverty ... and that is the principle of Profit Sharing where workers can have a vested interest in the company where they work:
Then rules and laws should be established to regulate the excessive fortunes of certain private individuals, and limit the misery of millions of the poor masses; thus a certain moderation would be obtained. However, absolute equality is just as impossible, for absolute equality in fortunes, honors, commerce, agriculture, industry, would end in a want of comfort, in discouragement, in disorganization of the means of existence, and in universal disappointment: the order of the community would be quite destroyed. Thus, there is a great wisdom in the fact that equality is not imposed by law: it is, therefore, preferable for moderation to do its work. The main point is, by means of laws and regulations to hinder the constitution of the excessive fortunes of certain individuals, and to protect the essential needs of the masses. For instance, the manufacturers and the industrials heap up a treasure each day, and the poor artisans do not gain their daily sustenance: that is the height of iniquity, and no just man can accept it. Therefore, laws and regulations should be established which would permit the workmen to receive from the factory owner their wages and a share in the fourth or the fifth part of the profits, according to the wants of the factory; or in some other way the body of workmen and the manufacturers should share equitably the profits and advantages.
