Although many factory laborers in MDCs are paid $________ per hour, factory laborers in LDCs may be paid less than $________ per hour.

The text you provided is incomplete and does not provide specific values for the blanks. However, I can explain the concept behind it.

MDCs (More Developed Countries) and LDCs (Less Developed Countries) have different economic conditions, which affect the wages of workers.

1. In MDCs, such as the United States, Canada, or countries in Western Europe, factory laborers are typically paid higher wages. This is due to stronger economies, higher cost of living, and more stringent labor laws. The exact amount can vary widely depending on the specific country, industry, and the worker's level of skill and experience.

2. In contrast, factory laborers in LDCs, such as certain countries in Africa, Asia, or South America, may be paid less. These countries often have weaker economies, lower cost of living, and less stringent labor laws. Again, the exact amount can vary widely.

Without specific numbers, it's impossible to fill in the blanks accurately. However, the general idea is that factory laborers in MDCs earn more per hour than their counterparts in LDCs.
