I'd argue that many startups try to create new money too.
"The risk they take is minimal compared to startups - it's not their money (it's their investors),"
Not true. General partners also invest in the VC firms. It's not completely OPM
"and a nice cushy salary is all but assured for several years."
Also not true. In NYC, for example, 100K isn't exactly "cushy".
"Even when they fail (and they fail a lot - like most businesses do) - they barely feel each failure compared to how the startups feel it (I guess their reputation / pride takes a hit?)."
Back to the previous point, they lose the money they personally invested and they feel the failure when they turn around and try again.
