I'd agree in most situations, however, given that it's not uncommon for many at Amazon to move to Google, Microsoft, et al. we can make a general assumption that the average engineer isn't a "dangerously incompetent buffoon" (outliers can occur, but a whole team of such is very unlikely).

Also, OP is probably not nuts, more likely a narcissist as other have commented. Of course there's many posts out there stating that management is not functioning as it should - OP paints the same picture, however, the statement provided by the author also tells of continuously combative attitude.
