Answer:
People invest:
to increase future consumption.
Step-by-step explanation:
Investments generate increased returns. These returns add value to the pool of an investor's money which can be used to increase future consumption. Investments are important because they increase productivity of value. The increased value will be future use. For example, if A invests his savings of $5,000 which yields an annual return of $1,000 (or 20%) ROI, and the investment is left for 5 years, by the end of 5 years, A will have $10,000. This implies that he has more money to spend than in the previous five years. A can now spend more $5,000 than he could have spent five years' ago.
