McKinsey is the cause of a lot of issues...
It's all 20 something Ivy Leaguers that corporations pay a lot of money to be told the best path forward is:
Layoffs, cut benefits, give executives bonuses
Of course, they dabble in other shit as well.

When people complain about how capitalism is fucking shit up, there's usually some McKinsey employees (again, dumb rich 20 something's straight out of college) way back at the beginning of the problem telling everyone to do the thing that caused the problems.
They do an absolute dog shit job of helping, unless the only people you care about helping are the wealthiest. McKinsey always comes up with solutions that make the wealthy more money.
The wealthy already know those "solutions" they just need a third party to suggest it so when it hurts everyone else the wealthy can act like even the experts couldn't see the obvious downside coming.
