Although they make up less than 1% of the population, they are disproportionately represented among wealthy business owners. The Memons were traditionally a mercantile community rather than an agrarian one, they were primarily urban, engaged in trade and commerce instead of farming or manual labor. Over generations, this economic specialization allowed them to accumulate capital, experience and commercial networks, creating momentum that reinforced their success. Nepotism and in-group preference also contributed to this process by keeping capital within the community.
This pattern is not unique to the Memons. they are called "middleman minorities", communities that become disproportionately concentrated in commerce, trade, finance, or small business. like Chinese Indonesians, the Igbo of Nigeria and the Jews. These groups typically develop extensive family and diaspora business networks, exhibit strong in-group economic cooperation and maintain some cultural, linguistic, or religious identify that set them apart from the majority population.
Historically, European Jews occupied a similar socioeconomic niche. As a result they became disproportionately represented in commercial and financial occupations. Because Europe later became the dominant center of the global economy, Jewish communities accumulated considerable wealth and influence and became the most powerful middleman minority.
