Further, unless and until the spending-as-stimulus plan has specific employment targets (which it does not), there is no guarantee that companies will hire in proportion to the monies spent on "stimulus". There is not one single job or paycheck explicitly guaranteed anywhere in the text of the porkulus bill.
FDR's New Deal programs (WPA and CCC) were authentic "bottom up" stimulus efforts because they put people to work directly, put money in their pockets directly, and let their spending inject demand back into the economy. Dear Leader has proposed nothing of the kind.
President Bush's stimulus checks last year were authentic "bottom up" because they put money directly in the hands of taxpayers. Dear Leader has proposed nothing of the kind.
In fact, one of the biggest criticisms of the porkulus bill was and remains that Republicans, using Dear Leader's own pie-in-the-sky assumptions, showed that more jobs could be saved/created through a series of tax cuts with no additional spending. As job creation/salvation efforts go, Dear Leader's non-stimulus bill is a farce.
Also, as monstrous as the spending-as-stimulus obscenity is, it is the smallest part of the stimulative flailings Dear Leader has pursued. The greatest portion of his stimulative efforts are in the financial sector with the bailing out of AIG and Wall Street--yes, the programs were started in the Bush Administration, but Dear Leader is expanding upon and endorsing those efforts, and has co-opted them as his own. Efforts to stimulate lending and credit are not "bottom up" either, unless you're proposing Dear Leader give every American a government-backed Visa Card and encourage shopping sprees.
