"Under current policy, the United States has about 20 years for corrective action after which no amount of future tax increases or spending cuts could avoid the government defaulting on its debt whether explicitly or implicitly "
Thus far, the GOP has refused to accept the need for Tax Increases on Corporations and the Wealthiest Americans...until it does, we're like 'Thelma and Louise', racing toward the cliff.
btw...Democrats have already shown the way toward resolving this problem (e.g. Clinton's Economic Plan that resulted in a Surplus).
