The main concern for the world in 2010, as stated in a report by the World Economic Forum, is the possibility of government finances deteriorating and causing full-fledged debt crises. Major economies have responded to the financial crisis by increasing deficits through stimulus packages and supporting private debt, which has raised concerns in financial markets. Developed nations are particularly at risk, while many emerging economies in Latin America have already taken steps to address their fiscal issues. The rising levels of debt due to government stimulus efforts are increasing the risk of sovereign defaults, according to the WEF report. He mentioned that higher levels of unemployment could result, along with associated social and political risks. The report identified unsustainable debt levels and the potential impact of the financial crisis as key risks, along with underinvestment in infrastructure and the rise of chronic diseases like Alzheimer's and diabetes. Other looming threats included the possibility of asset price collapse, risks related to Afghanistan, and the potential slowdown in Chinese growth, which could have negative effects on employment, social unrest, and exports. The report warned about the risk of developed nations accumulating unsustainable levels of debt, stating that full-blown debt crises would have unavoidable social and political repercussions, including increased unemployment. Daniel Hofmann, the group chief economist at Zurich Financial Services, emphasized that government debt levels of 100 percent of GDP, which the United States and the UK are approaching, are clearly unsustainable. Investors may become fearful and question the sustainability of high debt levels, leading to sovereign debt crises and defaults. Dubai and Greece serve as early warnings that should not be ignored. Concerns over Dubai, Ukraine, and Greece are affecting global markets, and these countries, along with the United States and the United Kingdom, are facing pressure. The WEF report emphasizes the need for tough decisions to be made in the coming months regarding the withdrawal of fiscal stimulus to ensure a sustained recovery without causing fear of sovereign debt deterioration. The report also points out a "governance gap" between short-term pressures and the need for long-term decisions on issues such as health, pension reform, and climate change. The report mentioned that not enough was being done to deal with the lack of investment in infrastructure, which could harm food and energy security. According to the World Bank, global infrastructure investment needs over the next 20 years are estimated to be $35 trillion. The report also highlighted the increasing financial burden from chronic diseases due to greater life expectancy and unhealthy lifestyles, and suggested that prevention campaigns promoting healthier living are necessary for both developing and developed nations to address this issue. The report warned that the biggest risks facing the world today may come from slow failures or gradual risks, as the impact of these failures and risks can be significantly underestimated due to their emergence over a long period of time.
