I have included some key points for those who cannot get past the pay wall or find the piece on another site.
“A zombie idea is a belief or doctrine that has repeatedly been proved false, but refuses to die; instead, it just keeps shambling along, eating people’s brains. The ultimate zombie in American politics is the assertion that tax cuts pay for themselves — a claim that has been proved wrong again and again over the past 40 years. But there are other zombies, like climate change denial, that play an almost equally large role in our political discourse.”
“Voodoo has also crashed and burned at the state level: The Kansas experiment in radical tax cuts was a dismal failure, while California’s tax hike under Jerry Brown, which conservatives declared a case of “economic suicide,” was followed by a revenue and economic boom.”
“Yet voodoo economics has become unchallengeable doctrine within the Republican Party. Even fake moderates like Susan Collins justified their support for the 2017 Trump tax cut by claiming that it would reduce the budget deficit. Predictably, the deficit actually exploded, and now exceeds $1 trillion a year.”
“The politics of climate change have followed a similar trajectory. Global temperature keeps setting records, while climate-related catastrophes like the Australian wildfires are proliferating. Yet a majority of Republicans in Congress are climate deniers — many of them buying into the notion that climate change is a hoax perpetrated by a vast international scientific conspiracy — and even those, like Marco Rubio, who grudgingly admit that global warming is real oppose any significant action to limit emissions.”
“Anyway, a result of decades of zombification is a Republican caucus that consists entirely of soulless opportunists (and no, the fact that some of them like to quote Scripture doesn’t change that fact).”
Krugman, IMHO, pretty much nailed it.
