Recent accounting and liability rule changes have made banks more jointly liable and responsible for due diligence of scams, I mean, SPACs. Admittedly, not every SPAC has been an outright scam, but it appears the majority of them turn out to be so with their very optimistic forward projections and statements. Of course, these changes occur after billions upon billions of dollars have been poured into these companies. It doesn't help that the PCAOB and SEC don't have much in the way of fines that they can issue, historically and recently speaking. The supreme court being inclined to challenge or basically to legislate against the authority of federal agencies to do anything not explicitly spelled out by the constitution when it suits the philosophies of the supreme court justices. In addition to a partisan supreme court and SEC and PCAOB being unable or unwilling to curb market excesses, many of my peers in accounting have done time at accounting firms and the SEC. These same firms are paid by the very same companies where these people end up working that the SEC oversees. I wonder where the conflict of interest is in this revolving door policy.
