As a result of modernization, more and more people tend to migrate from rural settlements to cities with the hope of searching for potential job opportunities and a better life. This trend leads to the increasing speed of population density in many metropolitan areas and poses an urgent housing problem in urban areas, which creates severe social repercussions. Some people suppose that only the government can solve these issues, while others argue that they cannot intervene in the free economy. From my perspective, I completely agree that lawmakers can draft laws that can solve this problem.
