Krugman: More Marcoeconomics (No, that’s not a misspelling of “macroeconomics”.)
Marco Rubios SOTU response also included a shout-out to Says Law:
Every dollar our government borrows is money that isnt being invested to create jobs. And the uncertainty created by the debt is one reason why many businesses arent hiring.
I know where he gets this stuff: its what the Heritage Foundation guys were saying four years ago. It was obviously wrong even then: we have an excess of desired savings over desired investment thats why the economy is depressed! so it makes no sense to assume that government borrowing must crowd out private investment dollar for dollar, or indeed at all.
But some things have changed over these past four years. Back then, the Heritage guys, Niall Ferguson, etc. made a prediction: those government deficits supposedly competing for funds with business would send interest rates soaring. Instead they hit record lows.
And we also have evidence on what happens when government try to slash deficits in a depressed economy. Heres IMF data for all advanced countries, where austerity is measured by the change in the structural budget balance as a percentage of potential GDP:
So Rubio has embraced an economic doctrine that was fairly stupid to begin with, and has produced ludicrously wrong predictions these past four years; this on top of accepting a completely bogus story about how we got into this mess in the first place. The GOPs savior!

When your policy is not based on facts but on oft-repeated lies, it is hard to change your policy in response to what actually happens in the world.
