In just two decades, America has added $25 trillion in debt. The biggest — and often bipartisan — drivers of debt have been the federal responses to two sharp economic downturns: the 2008 financial crisis and the 2020 pandemic recession. Shortly after Mr. Obama took office in 2009, inheriting a recession, he pushed Congress to approve a nearly $800 billion package of tax cuts and stimulus spending. Safety-net spending continued at high levels for the next several years as the economy recovered sluggishly. Mr. Trump approved a much larger collection of aid packages, totaling more than $3 trillion after Covid-19 swept the world in 2020. Mr. Biden took office the next year and signed a $1.9 trillion stimulus plan soon after.
