We need different names for different degrees.
There is absolutely no comparison between a PhD in physics, math, or engineering and a PhD in economics, education, or political “science”.
And those loons are ruining the title.
Not necessarily, the Ph.D.’s in the hard sciences use “science”, “technology”, the “scientific method”, “proof in the laboratory,” and other such terms to justify their own “science,” which is also often politically-driven in order to get liberal government grants. I understand a person can’t get a master’s degree as well as a Ph.D. in biology if he disbelieves in “evolution,” which they no longer consider “just” a theory but essential to the total understanding of biology. Government has corrupted all fields of knowledge with the carrot of popular “grants.”

I have to disagree.
After WWII, the power of science to understand and control the great forces of the universe was obvious and indisputable. This dismayed the irrationalists, who saw their control over the terms of "the great conversation" slipping away. The strength and confidence of America, its power to shape the world culturally and technologically, was a horrible setback to them.
It took many years for them to implement their response, but they are as patient as the Devil himself.
Part of their response was to debase the prestige of science. One of the ways this was accomplished was through the proliferation of all these bogus "sciences," economics and political "science" (as you rightly put it) being just two of these; you can, I'm sure, think of several others.
These fields attract wannabees, second- and third-raters, of whom John Maynard Keynes was a typical, humdrum example... except that his body of "work" gave politicians a license to expand central control over economies. For this reason, he has been virtually canonized by the elites, his nonsense taught to generations of fellow-wannabees in halls of higher learning built by the wealth of better men.
