"The $97.5 trillion price tag is made up mostly of the costs of Sanders’s three most ambitious proposals. Sanders concedes that his Medicare For All plan would increase federal spending by “somewhere between $30 and $40 trillion over a 10-year period.” He pledges to spend $16.3 trillion on his climate plan. And his proposal to guarantee all Americans a full-time government job paying $15 an hour, with full benefits, is estimated to cost $30.1 trillion. The final $11.1 trillion includes $3 trillion to forgive all student loans and guarantee free public-college tuition—plus $1.8 trillion to expand Social Security, $2.5 trillion on housing, $1.6 trillion on paid family leave, $1 trillion on infrastructure, $800 billion on general K-12 education spending, and an additional $400 billion on higher public school teacher salaries.
This unprecedented outlay would more than double the size of the federal government. Over the next decade, Washington is already projected to spend $60 trillion, and state and local governments will spend another $29.7 trillion from non-federal sources. Adding Sanders’s $97.5 trillion—and then subtracting the $3 trillion saved by state governments under Medicare For All—would raise the total cost of government to $184 trillion, or 70 percent of the projected GDP over ten years
Such spending would far exceed even that of European social democracies. The 35 OECD countries average 43 percent of GDP in total government spending. Finland’s 57 percent tops the list, edging France and Denmark. Meantime, Sweden and Norway—regularly lauded as models for the U.S.—spend just under 50 percent of GDP. The U.S. government, at all levels, spends between 34 percent and 38 percent of GDP, depending on how one calculates."
