Final answer:
Unethical behavior in the real estate and banking industries has contributed to a lack of trust in the free market system, as evidenced by the 2008-2009 Great Recession, where bank failures and financial stress led to widespread economic hardship and an uneven distribution of financial support.
Step-by-step explanation:
Unethical behavior in business, particularly in the real estate and banking industries, has had severe repercussions. Despite the significant role they play in facilitating transactions and the potential for economic gains, banks facing financial stress and declining asset values have the potential to cause widespread economic challenges. The 2008-2009 Great Recession demonstrated this, where the fall in housing prices and the recession made it difficult for many homeowners to make mortgage payments, leading to bank failures and a crisis in the banking sector. This scenario contributes to a general lack of trust in the free market system due to perceived injustice, where ordinary citizens faced foreclosures and job losses, while large financial institutions received government bailouts and continued high compensations for executives.
