Moreover, you’ll explore the role of government bailouts, lobbying, and the public’s lack of understanding of this convoluted industry.

Finance: A Blessing and a Curse

Finance was invented to improve our quality of life, help us conduct business, own property, and organize assets. A healthy financial system can benefit society, but capitalist freedom has led to financial innovations that are not always beneficial to us. The financial industry has lost sight of what’s good and bad for the global population as a whole, and this summary will delve into why this has occurred.

The Danger of Financialization

Financialization, the rampant trading activity and massive growth in the finance sector, has not had any positive impact on household income or small business growth. The emergence of derivatives, such as credit default swaps, has led to artificial inflation and ultimately contributed to the 2008 financial crisis. Financialization is akin to gambling and is not beneficial to anyone.


Gone are the days when finance existed to help people realize their ideas. Nowadays, the finance sector is drowning in needless transactions that serve no purpose. This is due to financialization, the rampant trading activity that has helped banks and stock markets but has had no positive impact on household income or small business growth.

This trend started in the 1970s when large institutions began trading in securities, which are financial assets such as stocks, bonds, and mutual funds. However, the real trigger for financialization was the emergence of derivatives, which are contracts that base their value on how well other assets perform.

One example of a derivative is a credit default swap (CDS), which allows a bank to protect itself against a borrower defaulting on their loan or mortgage. But this can quickly turn dangerous as too many institutions invest in CDS. This is what happened in the 2008 financial crisis. Too many banks gave loans to people who were unable to honor them, and multiple people defaulted on their loans. The system collapsed upon itself.

The financial crisis was escalated by technology that made trading securities and derivatives easier than ever, leading to massive artificial inflation of the financial sector. Such practices are akin to gambling, which isn’t beneficial to anyone. It’s important to remember that finance should help people realize their ideas, not drown in needless transactions.

Financialization and the Volatile Economy

The finance sector’s culture of risk-taking and short-term gains has led to a less stable economy. In the past, banking executives had a personal investment in their banks, leading to more caution and reliable decision-making. However, in the era of financialization, executives prioritize short-term gains and do not act in the best interests of their banks. This has resulted in granting mortgages to unreliable borrowers and brokers making deals that benefit themselves over their clients.

In the past, the financial sector promoted a culture of caution and planning, leading to a more stable economy. This was due to executives investing their personal funds into their banks, giving them a personal stake in avoiding failure and risky decisions. However, the era of financialization has resulted in a more volatile economy, as executives prioritize short-term gains and are not incentivized to act in their banks’ best interests. This has led to the granting of mortgages to unreliable borrowers, contributing to the financial crisis of 2008. Additionally, the shift towards broker-dealers making their own deals has led to conflicts of interest, as brokers prioritize their own profits over their clients’ best interests.

The Root Cause of the Global Financial Crisis

The 2008 global financial crisis was not an unforeseeable disaster, but rather a predictable outcome resulting from years of risky and selfish decisions made by bankers driven by insatiable greed. The shift from private to corporate ownership of banks allowed executives to take greater risks with shareholders’ money while being unaccountable for any losses incurred. The dangerous practices of mortgage-backed securities and credit default swaps only added to the destabilization of the financial sector. The crisis was caused by the offering of mortgages to people who could not afford them and the trading of securities based on those mortgages, leading to both banks’ inevitable downfall and subsequent bailouts by national governments.
