This kind of behavior is no different than basic criminal behavior or a child's behavior. When you do something that you know is wrong or shady but it benefits you, and you experience no consequences for it, you do it again and again, as long as two things remain in place: 1) It continues to benefit you and 2) You remain consequence-free.
The outcome of the above leads to more brazen behavior - while you used to sneak and do it, you are more flippant and less cautious, because you are less worried about any negative repercussions.
This is exactly what we're seeing. For well over a decade, there have been no consequences to runaway spending and massive debt accumulation. Central banks have "got it" and MMT provides a psychological safety net.
One day, it will absolutely crash and burn. But you better believe they are going to swing for the fences right up until the very end. When the consequences come, it will be too late...and they will be severe.
By the way, like you noted above, nice gravestone doji to end the day!
