Debt crisis in the context of Tax revenues

The euro area crisis, often also referred to as the eurozone crisis, European debt crisis, or European sovereign debt crisis, was a multi-year debt crisis and financial crisis in the European Union (EU) from 2009 until, in Greece, 2018. The eurozone member states of Greece, Portugal, Ireland, and Cyprus were unable to repay or refinance their government debt or to bail out fragile banks under their national supervision and needed assistance from other eurozone countries, the European Central Bank (ECB), and the International Monetary Fund (IMF). The crisis included the Greek government-debt crisis, the 2008–2014 Spanish financial crisis, the 2010–2014 Portuguese financial crisis, the post-2008 Irish banking crisis and the post-2008 Irish economic downturn, as well as the 2012–2013 Cypriot financial crisis. The crisis contributed to changes in leadership in Greece, Ireland, France, Italy, Portugal, Spain, Slovenia, Slovakia, Belgium, and the Netherlands as well as in the United Kingdom. It also led to austerity, increases in unemployment rates to as high as 27% in Greece and Spain, and increases in poverty levels and income inequality in the affected countries.

Causes of the euro area crisis included a weak economy of the European Union after the 2008 financial crisis and the Great Recession, the sudden stop of the flow of foreign capital into countries that had substantial current account deficits and were dependent on foreign lending. The crisis was worsened by the inability of states to resort to devaluation (reductions in the value of the national currency) due to having the euro as a shared currency. Debt accumulation in some eurozone members was in part due to differences in macroeconomics among eurozone member states prior to the adoption of the euro. It also involved a process of cross-border financial contagion. The European Central Bank (ECB) adopted an interest rate that incentivized investors in Northern eurozone members to lend to the South, whereas the South was incentivized to borrow because interest rates were very low. Over time, this led to the accumulation of deficits in the South, primarily by private economic actors. A lack of fiscal policy coordination among eurozone member states contributed to imbalanced capital flows in the eurozone, while a lack of financial regulatory centralization or harmonization among eurozone member states, coupled with a lack of credible commitments to provide bailouts to banks, incentivized risky financial transactions by banks. The detailed causes of the crisis varied from country to country. In several EU countries, private debts arising from real-estate bubbles were transferred to sovereign debt as a result of banking system bailouts and government responses to slowing economies post-bubble. European banks own a significant amount of sovereign debt, such that concerns regarding the solvency of banking systems or sovereigns are negatively reinforcing.

Shays's Rebellion was an armed uprising in Western Massachusetts and Worcester in response to a debt crisis among the citizenry and in opposition to the state government's increased efforts to collect taxes on both individuals and their trades. The fighting took place in the areas around Springfield during 1786 and 1787. Historically, scholars have argued that the four thousand rebels, called Shaysites, who protested against economic and civil rights injustices by the Massachusetts government were led by Revolutionary War veteran Daniel Shays. By the early 2020s, scholarship has suggested that Shays's role in the protests was significantly and strategically exaggerated by Massachusetts elites, who had a political interest in shifting blame for bad economic conditions away from themselves.

In 1787, the protesters marched on the federal Springfield Armory in an unsuccessful attempt to seize its weaponry and overthrow the government. The federal government, severely limited in its prerogatives under the Articles of Confederation, found itself unable to finance troops to put down the rebellion; it was consequently put down by the Massachusetts State Militia under William Shepard, alongside a privately funded local militia led by former Continental Army officer Benjamin Lincoln. The widely-held view had already developed that the Articles of Confederation were untenable and needed amending, with the events of the rebellion serving as further evidence for the later Constitutional Convention. There is continuing debate among scholars as to what extent the rebellion influenced the later drafting and ratification of the Constitution.

The 2010–2014 Portuguese financial crisis was part of the wider downturn of the Portuguese economy that started in 2001 and possibly ended between 2016 and 2017. The period from 2010 to 2014 was probably the hardest and more challenging part of the entire economic crisis; this period includes the 2011–14 international bailout to Portugal and was marked by intense austerity policies, more intense than the wider 2001-2017 crisis. Economic growth stalled in Portugal between 2001 and 2002, and following years of internal economic crisis, the worldwide Great Recession started to hit Portugal in 2008 and eventually led to the country being unable to repay or refinance its government debt without the assistance of third parties. To prevent an insolvency situation in the debt crisis, Portugal applied in April 2011 for bail-out programs and drew a cumulated €78 billion from the IMF, the EFSM, and the EFSF. Portugal exited the bailout in May 2014, the same year that positive economic growth re-appeared following three years of recession. The government achieved a 2.1% budget deficit in 2016 (the lowest since the restoration of democracy in 1974) and in 2017 the economy grew 2.7% (the highest growth rate since 2000).
