The thing is, the logical conclusion of Keynesian policy is that it's ultimately impossible to know when there are "good times." Thus, the constant overspending by the government is a logical conclusion of Keynesianism because central planners will never get their predictions right. - vagabondvet
I went to an astrologer once to "get a reading" (before you judge, it was a friend and I was curious). On a few points in the interview, I asked questions that were apparently a little too specific. She shuffled around her half-crumpled papers with scribbles and symbols and would eventually point at one random spot in the gibberish and proclaim "Ah! Here we go. As you can see, this calculation here indicates that ______."
I'm embarrassed to say that I actually knew a thing or two about how the calculations were done and gently inquired about why she was pointing at things that clearly had no relevance to what she was saying they did. At one point she rotated the paper 90° and started talking about "seeing through the numbers" and then defensively reminded me of how long she'd been doing it and her "results."
Our overlords can see through the numbers. It's best to just take their word for it and go about your business.
