The $787B mistake:

…the 1930s Keynesian model that was used to sell the idea of fiscal stimulus to Americans was eliminated from economics decades ago.

And this abandonment of Keynesian multipliers does not reflect any ideological or partisan issues that divide conservatives and liberal economists. Rather, it is because the old Keynesian model does not come anywhere close to meeting today’s standards for economic analysis…

…modern economic analysis shows that the impact of government spending on the economy depends on what it is being spent on and how it ultimately is paid for.

The upshot of this new research is that multipliers are nowhere near the numbers that were cited in support of ARRA and, in fact, can be negative, depending on how the spending is ultimately financed. Robert Lucas, the 1995 Nobel laureate in economics who specializes in macroeconomics and government policy, recently remarked that the promise of large multipliers presented by private macroeconomic consulting firms in support of ARRA was “schlock economics.”

One of the infuriating things about the rush to passage of that disastrous legislation was the continual lies, from people like Ed Rendell, and Chuck Schumer and others, that most economists agreed that it was essential to recovery when, at best, there was merely a consensus that something should be done to soften the blow of the financial implosion, but not ARRA. And the media, of course, never called them on it. And of course, the president and others trotted out their usual straw men, and false choice, saying that anyone who didn’t want to implement that legislative atrocity wanted to do “nothing.”

Simply suspending the payroll tax for the rest of the year would have been a lot more effective, and cost a lot less, without creating this huge new tidal wave of debt in the out years.

[Lunchtime update]

Rasmussen: 45% say cancel the rest of the stimulus spending. Only 36% disagree. Expect that number to go higher. And that’s not “adults.” It’s likely voters. Democrats will ignore this at their peril next election season.

And note this:

A plurality of government employees believe speeding up the stimulus will be good for the economy. However, those who work in the private sector strongly disagree.

In other words, the people who understand how the economy works (because they’re the ones who make it work) are opposed to this, while the people who get their money from it are in favor. The goal of the Big Government party (on both sides of the aisle) is to increase the latter and decrease the former, not understanding that, eventually, this will cause the collapse of the nation.
