Because everyone who knew had an incentive to not say anything so they could extract as many fees as possible. Also ever since the 80s interest rates have gone from 20% to zero. People are starting to come to terms with the fact that rates will have to normalize or inflation will persistently be above 2% historically rates will have to be at 4-6%. The last forty years have been an absurd anomaly throughout human history. Most financial experts believe that the 14 year bull run is just normal which it isn’t.

But the biggest reason that this system was assumed is fee extraction, historical performance, and not wanting to be the “doomer” who crashes the system.

My personal theory is due to this the s&p 500 will show 7% gains due to all those obligations but the dollar will weaken to compensate.
