The financialization of the economy has brought about patterns of inequality, cultural and social change.
Underpinning these changes is a particular shift in how capital is intermediated. The success of the financial sector has led to the failing of the ‘real economy’, existing of companies and individuals that produce goods and services which add real value to the economy.
A great metaphor is made by M. Hudson, who compares the financialization of the economy with how parasites control a host’s brain.
Financialization is defined as ”the increasing role of financial motives, financial markets, commercial actors and financial institutions in the operation of the domestic and international economies.”  Power ultimately tends to flow towards the lenders (wealthy individuals, banks and financial institutions). So, in the end, the borrowers lose control of their systems – which become fundamentally less democratic.
One of the topics which are frequently associated with financialization is increasing economic inequality.
Research has shown that the phenomenon of growing financialization further boosts income inequality. Revenues from financial investments are, for the most part, not reinvested in the businesses that make up the bedrock of the real economy. Moreover, one of the consequences is that wages of workers stagnate and wage-earners are ever more indebted.  Also, most of the returns made by the financial sector go to the concentrated financially prosperous, further driving inequality in society. Therefore, this trend has essentially turned the United States from a nation of savers into a nation of borrowers. Personal savings are declining, and consumer debt is replacing the gap. It is created by stagnant or declining income (versus the ever-increasing cost of living).
Economic polarization on a bigger scale is occurring between creditor and debtor nations on the international level. The Eurozone, for example, is being divided with Germany, Netherlands, Norway, Sweden, Switzerland in the creditor camp, while Greece, Spain, Portugal, Ireland and Italy are sinking deeper into debt, unemployment and austerity – followed by social unrest, emigration and or capital flight.
Western countries used to have a booming real economy that went through periods of industrialization and expansion, flourished with a thriving middle class.
Research and development enabled the development of new technologies. So, it increased the productivity of the labour force. Moreover, it resulted in higher wages and generally created a more prosperous economy. This thriving economy slowed down significantly once the process of financialization began.
In the last decades, a considerable amount of (intellectual) energy went into the optimization of financial engineering. In turn, financial engineering has – for the most part – led to a stressed, over-indebted and fragile system. Where profits are made mainly in the financial sector. If only finance took back its supporting role, in the background, facilitating the development of the “real”, physical economy. So, it would have been a different story altogether. Will it truly take a major crisis, for finance to abdicate, and relinquish its leading role in the global economy?
