Yes, I remember Keynies say it was impossible. Yet we had 4 years of Carter's "malaise", not to mentions double digit mortgage interest. I remember, because we were looking at buying a house at the time. 18% or more interest on a mortgage? Really? We gave up and kept renting.
So, similar to the same old tired media and self-agrandizing Phd's spouting we were heading into a new ice age (Time magazine proclaimed so in the '70's); or a population bomb where almost half the world would die from starvation (Newsweek or maybe Time proclaimed such); or that there were no differences between boys and girls (pretty sure that was Time rag); and now try to claim the worlds is going to die from human global warming.
Sorry for the run-on sentence.
I try to be fair, and watch CNN occasionally, but saw some pundit was talking about "global warming" because of the awful smog in China. He said, "This is undisputable proof that we humans are causing the planet to warm". Yes, the smog in China is really bad, but to extrapolate that to rising seas that will flood every coastline is just damn ridiculous.
What he didn't bother to mention that even the "global warming" mongers at the IPCC mentioned in their latest report that there has been NO to ANY significant increase in global warming in the last 15 years. Of course, it was at the end of the report.
Who gives these people their doctorates? Sheesh, I'm a GED person and can read between the lines and add 2 plus 2 regarding Sun activity. Apparently, academia is failing everyone, including the teachers. Like that's news.
The above said, pretty much believe that anyone with a new theory about anything and articulate well in writing get a doctorate. If it works within the mindset of the collective professors, than you're good to go. Right or wrong. Just write what your professors want to hear.
