Final answer:
The revenue from associated services can sometimes exceed the revenue from the products themselves, particularly in the service sector.
Step-by-step explanation:
In many cases for industrial products, the revenue from associated services does indeed exceed the revenue from the products themselves. This is particularly true in the service sector, where the value-added profits are not as high as in the manufacturing sector.
For example, the gaming industry, such as casinos, may not generate significant national income. However, it creates numerous service jobs. On the other hand, manufacturing activity often generates large unit profits or value added per unit, and a substantial portion of these profits may return to workers as high wages.
Overall, the service sector contributes significantly to employment opportunities and income generation in industrialized countries. The revenue from associated services can sometimes outweigh the revenue from the products themselves, especially in industries that rely heavily on service provision.
