"We shouldnt accept the premise that the government owns the entire economy; hence GDP should not be considered the governments income in a given year. If were going to pick a specific number, the proper analog would be federal receipts."

"Even if it were true that a private corporation would take on more debt, if it were currently wearing Uncle Sams shoes, that alone wouldnt be sufficient to seal the argument. This is because government debt involves present citizens living at the expense of future taxpayers, who may not even be alive yet to argue about the decision."
