How does the absence of the rank-size distribution in an LDC indicate that there is not enough wealth in the society to pay for a full variety of services

The regular distribution observed over some more developed countries (MDCs) is not seen in less developed countries (LDCs). Geographers explain this difference and why the absence of a regular pattern is significant.

The regular pattern in MDCs reflects where services are provided in MDCs,the majority of the workers are employed in tertiary sector of the economy, which is the provision of goods and services for people in exchange for payment. In contrast, less than 10% of the labor force in LDCs provide services.
