The evil-evils don't meet in shadowy mansions with bad lighting and creepy piano music. They meet in private parties in Aspen and executive boardrooms and on the boards of "charities" that really exist as a scoreboard for the social status of rich people. They also don't have huge orgies. They visit prostitutes half their age whom they pay $1500/night to endure their post-coital crying about their mistakes (such as marrying dumb trophy/corporate wives and having to write high-six-figure donation checks to shove their low-IQ kids into Ivies).
There isn't "one conspiracy to rule them all", but there are lower-case-c conspiracies all over the place.
