The government collects only $2.66 trillion in taxes but spends $2.36 trillion just on Social Security, Medicare, Medicaid, food stamps and the like, summed up as Personal Current Transfer Payments.
If we ran a balanced budget, that would leave just $300 billion for everything else, such as defending the country from our enemies, for which we actually spend about $700 billion currently.
Total current expenditures are running at $3.8 trillion, nearly 41 percent more than we presently take in.
