Comment Tell us you know nothing of macroeconomics (Score 4, Informative) 153
There is no single or even leading theory of macroeconomics, but there are several strong schools and some agreed upon basics and underlying mechanisms. Whenever a technology person starts fulminating about "national debt" and "our national debt will bankrupt us", with us being the United States, it tells me they know nothing of macroeconomics, the leading theories of national debt, or the role of the US national debt in light of the role of the US dollar as the global reserve currency.
tl;dr: technobabble baloney
