Answer:
have a mechanism capable of attracting savings and channeling them into wealth-creating projects.
Step-by-step explanation:
The single most important factor that fosters economic growth is productivity. Increasing productivity refers being able to produce a larger amount of output using the same amount of resources or producing the same amount of output using a lower amount of resources.
Productivity generally increases by investing in labor (e.g. more education, more training, better health care, etc.), by increasing capital (e.g. more factories, equipment, machinery, etc.) or by investing in the research and development of new technologies (e.g. artificial intelligence, automation, etc.). What all of these ways of increasing productivity have in common, is that they require more investments in the economy.
The only way to have more money to invest is to save more. In economics, savings = investments. Money that you do not spend in the present, can be invested so that in the future your wealth increases. The same logic applies to countries, where more investments = higher and more stable long term economic growth.
