No doubt much of this is true. I don't "clock in, clock out" - I am 24/7 as someone in this thread already said. I have conference calls at 11 pm, 4 am, 6 pm, etc -- some days I don't sleep. I have executed dozens of M&A transactions where I've led teams of hundreds on diligence, negotiation of definitive agreements, internal reorganizations, private equity capitalizations, etc. There is no question that someone off of the general floor could not simply substitute for me on those types of transactions, as they are far outside of the ordinary course of business.
All that said, I do not think a world where I am paid 250 times one of those employees is a fair one. There's a limit to what I need or my family (or generations down) really need. My employees should not have to worry about purchasing an extra gift or two for their kids while I think about whether I want a third or fourth house in Telluride. I think anyone who thinks otherwise is just operating on greed. That's just my opinion- if others feel differently, do you.
