“I can live well alone!” is not correct. If I live alone, I can survive to some extent, but ultimately, it is hard to survive, and “living well” is even more challenging. This is because the economic principle is established not by ‘alone’ but by ‘many people.’ If I live well, it means that someone has become poor because of me or is living well with me. The fact that through value exchange, or transaction, we can meet each other’s needs and store the surplus from that production is both true and real. Trading is not done in isolation. - Joseph’s “just my thoughts”
Architecture has developed in response to the epidemic. The city was designed to mitigate the risk of outbreaks. However, its high population density renders it susceptible to epidemics. A potential solution to this issue involves the construction of a water supply and sewage system, which safeguards individuals from waterborne infectious diseases (e.g., cholera) by effectively separating and burying water and sewage underground. Nonetheless, the advent of vaccines has facilitated the existence of megacities with populations exceeding 10 million people. Indeed, microorganisms predominantly populate the Earth. - Joseph’s “just my thoughts”
