They let fraudsters (pigs) accumulate capital by any means. Then they butcher it for political and financial capital. Government looks like a hero and they are able to keep the lights on.
In China, this has been going on for a while (ex. evergrande, HNA, Silicon Valley Bank, Tether) and online sleuths have uncovered crypto projects/funding from China are also another "western pig butchering".
SBF, Do Kwon are similar to Truong My Lan in that they are also "useful pigs" with many smaller "pigs" below them pulling capital into a "jurisdiction tor network". Some pigs are on the spectrum and do not require greed as motivation, simply the fame and recognition from having created "something" for other pigs is enough.
