Investing contributes to economic growth primarily through the following ways:
- Investor funds are loaned to firms, who use borrowed funds to purchase capital. Funds from investors are used by firms to purchase capital which leads to economic growth. This option highlights how investments can facilitate the acquisition of capital goods, which are essential for production and expanding business operations, thus driving economic growth.
While the other options discuss aspects of investing, such as earning returns and diversifying portfolios, their direct connection to fostering economic growth is less pronounced than the one regarding funds being loaned to firms for capital investment.
