The global economic crisis, including the one in Central and Eastern Europe, originated from the deregulation of the financial market by leaders like Reagan and Thatcher. This led to excessive risk-taking by investors and banks, causing the subprime crisis. The lack of oversight in the banking system worsened the situation. The crisis was fueled by a belief that the market could correct itself, leading to a real estate market collapse. The interaction between people's perceptions and reality caused market deviations, ultimately leading to an unsustainable situation.
