Both Peale and now Trump work their snake oil medicine wagons effectively resulting in virtually lobotomizing anyone adopting their vacuous tripe devoid of any useful awareness of facts and details. Their solutions amount to pushing boulders uphill at someone else’s behest.

The mass effect of their followers and admirers on society, in the long run, could be compared to any individual's actual lobotomy, and how did that science work out?

It’s eerily similar to followers of Ayn Rand’s philosophical ideas of over-regulated capital markets and how society as a whole will not benefit from that regulatory interference. I believe that bullshit hit the fan big time in 2007–2008, hopefully, we learned who benefits from sane regulation.
