The reason why the smoothing is useful is that without it the public would form the mistaken impression every December that the economy is suddenly booming, only to be horribly disappointed every January. Or when students in June start their summer jobs there would be euphoria at all the hiring and then depression in September when hundreds of thousands suddenly left the labor force.
If they didn’t use seasonal adjustments when they report the data, you would need to apply your own just to discount the obvious cycles that occur every single year. It makes sense, and they also report the unadjusted number too, if you prefer that one. But one thing it’s not is a conspiracy.
I trust the public to form their own conclusions. It seems most of them have long been aware of Christmas.
Summer jobs? You’re having a laugh.
At the risk of belaboring the point, the statisticians are working for the government and overwhelmingly vote Democrat. Their support of Obama ranging from mundane stickers and buttons to financial support is documented.
The numbers have been questioned, even mocked, by persons far more learned in economics than I. The successes are conveniently timed and conveniently meet this or that threshold. Conspiracy? Not in terms of explicit instructions or coordination. Bias? Without question.
