With the large population of these two countries, the economic chain will continue to run because everyone definitely needs the food they buy every day, so that food and clothing makers will continue to run more stably. Because each of them also has to work in order to earn money for their own needs, so the large number of people living in these two countries will certainly make the country's economic turnover continue to increase quite well. And it will also be easier for anyone to take advantage of jobs that can make more money.
In my view, this isn't about monetizing a large population's capacity to purchase items, but rather, it's about the mindset of the population. A smaller population with a strong human resource base can make a more significant and positive contribution compared to a larger population with lower human resource quality. We can actually discuss the productivity of the population more than their consumption patterns.
Let's reconsider the idea of monetizing the domestic population to buy goods or exporting products to bring money into the country. Upon closer examination, it's better to be a producer rather than focusing on being a consumer. In doing so, the national income will rise, and the welfare of the society will improve.
