Yes, Mark would feel fine since all clients got back their money. But he would lose his firm, in worst case get just $1 after the IPO
You're OK with Mark feeling fine? I want him to feel the pain he has caused. And I want that to be in the back of the mind of every exchange owner.
The bankers felt fine after destroying the world economy and receiving a bailout. How is that working out?
the whole idea in the OP is not too dissimilar to something that an incompetent CEO may suggest himself, after failing miserably as a businessman.
