If the U.S. mainstream media was not owned and operated by the same 1% that purchases the politicians that drive policies favorable to their insatiable, greed-driven agendas, THIS fact would be stated often:
"The Safety Net costs us $370 Billion.
But Tax Avoidance costs us $2,200 Billion (tax expenditures, tax underpayments, tax havens, and corporate nonpayment). That's $2.2 trillion, six times more than the safety net, most of it benefiting the wealthiest Americans."
However, since a Captured Media prefers to traffic in lies told often, bastards like Paul Ryan, Scott Walker, Chris Christie, Rick Scott, et al get away with murder... in slow motion.
From the article:
"Beneficiaries of low taxes and deregulation desperately want to believe that "trickle-down" works, or at least to convince middle America that it works. They want to believe, against all logic, that lower taxes mean more tax revenue."
I don't think the motivation rests on what these individuals want to believe. It's what they can get away with... when wealth is directed to those least in need while suffering proliferates, then a CON of enormous proportions is underway. The cons have to lend a patina of legitimacy to what they're doing, so they set up economic theories and pundits who advocate them. It's the same strategy as parading 4-star generals as they LIE cases for war, or legal "scholars" who argue FOR torture, or corrupt scientists who argue that global warming is a myth.
Deception is currently in overdrive. Without balance governing the nation's government, laws, would-be checks and balances, or mass media's dominant and repeated often narratives... it becomes almost impossible to prove the degree of fraud let loose.
