The significance of finance lies in the effective distribution of funds. According to economics, there are many productive resources, such as land, labor, technology and capital. If the funds are invested in meaningful places, the production efficiency will be higher and more good things will be produced for people to use (GDP). No matter who handles the effective allocation of funds, whether it is banks, securities or anything, it is to send funds from the idle side to the side that needs funds for production. The recipient may be studying a new drug, creating a new app, or an ordinary steel factory, but it is also producing steel, providing employment opportunities and helping the society run. When they receive funds, they can produce and help society move forward. Without funds, their people don't need new drugs, new applications and steel bars to build houses. This is the contribution of finance. This is the contribution of every financial practitioner to society. Of course, what they do is very useful, and they make a lot of difference from it, so people in the financial sector are also rich. They not only benefit the society, but also benefit themselves and their families. However, if we can't correctly identify the risks and who are the "right" people who need funds, they will also bring crisis, unemployment, imbalance and depression to society. A typical example is the financial crisis in 2008. Therefore, the "professionalism" of financial practitioners is also very important, and integrity, management means and ability are all important. In short, becoming a professional financial practitioner is a contribution to society.
