The wealthy business class
This Civilization theory shows that the constituent parts of capitalist civilizations are essentially expressions of natural aspects of humankind's animal nature. These wealthy business class folk are those who either through heredity or through ambition and luck become powerful. Instead of natural hierarchies alone, the humans have evolved to use money as a physical measure of social power, where stronger people are those who either inherit money or who earn it successfully through business.
The impoverished working class
There is another narrative role for those who are less fortunate. Instead of showing poverty as an issue of imbalance or disenfranchisement, the narrative of capitalism is often that people who are poor chose to be poor through laziness. If they were brighter or harder working, so goes the narrative, then maybe they would get promoted, or perhaps they would even start businesses. By shaming the poor into working for employers, a workforce is guaranteed for the people who are really earning money, the business owners.
Scientists and inventors
The issue of technology is involved in this animal game of sexual and social power and currency. This happens because by technological improvement, companies can improve the quality of life for the civilization, and then by selling that improvement to the people, they can accrue immense monetary gains which they then use to impress attractive mates and build families with the most desirable physical traits (this is Marcuse's theory). The issue for the scientists is that economic interests often shape their work because companies often fund only the research that leads to economic progress.
