What happened to all European Countries expenditures from 1908 to?

From 1908 onward, European countries experienced significant fluctuations in expenditures due to various factors, including two World Wars, economic depressions, and shifts in political structures. Post-World War I, many nations faced high reparations and reconstruction costs, while the Great Depression in the 1930s led to increased government spending to stimulate economies. After World War II, European countries embarked on extensive reconstruction efforts, leading to the establishment of welfare states and increased public spending, particularly in health and education. The integration of European economies in the latter half of the 20th century also influenced expenditure patterns, with a focus on collaborative projects and infrastructure.
