The sub prime crisis is almost a perfect example of this actually. Why stuff bonds with shit? Because there are buyers who will spend 1bn dollars on a bond tranch without doing 10k in analysis of the underlying. Not just some buyers, a huge market of them. If people had done a little due diligence 5 years earlier, the crisis would have been 20 times smaller. It would have been a minor story on page 27 of the finance section.

Social media algos are the same. They recommend conspiracy bs because there are 1million morons glugging it down for every developer pushing it. They fund his bonus cheque. That's none of my business until they go out and vote or refuse to wear a mask...
