Final answer:
The ARRA contributed to economic recovery by injecting $800 billion into the economy through tax rebates for households and fiscal stabilization funds for states, aiding in job creation and stimulating consumer spending.
Step-by-step explanation:
President Obama's American Recovery and Reinvestment Act (ARRA) helped the U.S. economy recover from the Great Recession by committing nearly $800 billion to stimulate economic growth and job creation. This Act included tax rebates to low- and middle-income households, aimed at encouraging consumer spending, and provided fiscal stabilization funds to aid states and localities facing budget deficits and layoffs. Additionally, the ARRA's wide-ranging initiatives helped prevent layoffs and wage cuts, especially within struggling industries like auto manufacturers, contributing to the sector's profitability by 2011.
