I know nothing about nothing but here it goes:
Kurgman's position isn't 'party hard on a credit card, let our kids pay for it'. It's a pragmatic observation that if you drastically slash spending in a sluggish economy to balance the budget, you'll inevitably tank the economy and thus also reduce tax income - leaving you with a deficit again plus a nasty recession. And a ginormous debt that we already have that our kids will inherit minus any means to ever pay it down.
Economy is not a zero sum game. Government doesn't (just) spend money on hookers and blow, it educates the next generations of our workforce, builds crucial infrastructure, funds early (commercially unviable) r&d that will power the economy that our kids will work in. That's not wasteful spending that our kids will have to pay for, it's a crucial investment in their future.
Now I believe that the economy is a ridiculously complex, recursive system that we just can't model. Both Keynesians and Austrians latched onto different bits that kind of make sense but neither can guarantee what's going to happen 10 years from now. Interestingly I think there's little disagreement about the effects of 'real' austerity - the death spiral of the current system. From what I can tell, that's kind of the goal of many austrolibertarians - they want to rebuild from there on their (somewhat idealistic) principles. Growing up on the wrong side of the iron curtain has left me deeply suspicious of idealists
.
TLDR: we appear to be on course to economic Armageddon
Austrians: nuke it now and start over with gold!
Keynesians: poke it like we always did but harder! If that doesn't work, it'll nuke itself
