@OP When you're in an email thread or live call that shows their lack of tact, understanding of healthcare, basic business knowledge, or understanding of human empathy beyond the Indian subcontinent, call them out.
No, not like a j3rk, but asking questions in an elementary way that makes you sound a bit ignorant but deferring to their wisdom and authority to educate you. This baits them. This frustrates them when they have to explain their id1ocy. It further erodes their credibility among other leaders.
This works in a group setting and you can only do it if you've otherwise ingratiated yourselves to others so they do not perceive your sn@rk.
The house of cards is built on manipulation and buddy system. I guarantee any face you see on a screen or bouncing 100x like Tigger is playing along and is well protected. The stock could go to $100 and there are no repercussions internally.
The only way to fix this mess is frustrating them to take their ball and go home... or to do so yourself. Optum will be gone within 2-3 years unless SD and his clowns are gone in 3-6 months.
