It is "irrational" for a "greedy" slaveowner to kill their slave, a significant monetary investment sometimes, and yet it happened all the time, because capital owners are not rational.

A significant fraction of aviation fatalities can be traced directly back to those "greedy capitalist villains" actually completely cutting corners to save a penny and losing million dollar aircraft.

Business owners are not rational actors, they are gamblers.
