Final answer:
U.S. mass producers focus on long-term income and return on investment, while Japanese producers see the process with a short-term perspective.
Step-by-step explanation:
In terms of long-term income and return on investment, U.S. mass producers tend to focus on these factors. They prioritize expanding production over several years, and are willing to invest in building new factories, hiring new workers, and opening new stores to achieve this growth. On the other hand, Japanese producers have a short-term perspective on the process. They may be more cautious about investing in long-term expansion and instead prioritize immediate profitability.
