You are so full of shit. You just did a random Google search hoping you would find a claim to the contrary. That article is bullshit. It doesn't even come up with an actual figure. He just speculates. And even if the actual number is shy of 24 billion, it would still be well above half of a billion so quit your bitching about Solyndra.
What the Forbes article quite correctly points out is that simply because money isn't spent on
A doesn't mean that it isn't subsequently spent on
B. The money that people didn't spend on vacations to National Parks didn't vaporize in their wallets. Chances are that money was spent ELSEWHERE. The 24 billion dollar loss to the economy is what is "bullshit" because it's based on faulty assumptions.
As for Solyndra? The decision to reward Solyndra all of that tax payer money was bad management of our tax dollars by this Administration. PERIOD! They fucked up. PERIOD!
