My new question that Google refuses to answer

I've recently tried researching a topic that's hard to pose as a question to Google: which jobs pay the most per hour of work? For instance, many high paying jobs require ludicrous hours. Also, most high paying jobs require expensive training, which if you consider the opportunity cost of not working, that's really deductions factored in to the hourly rate. But for some jobs, all that training really pays off, for instance a surgeon can do one procedure and earn enough for a down payment on a house. On the other hand, some jobs allow for one time work that gives residual income requiring little or no further work or even marketing, like app development. Plus, some jobs may at first require ridiculous hours, like starting your own business, but then you can sell it for a boatload. So now I pose this question to you blogosphere and twitter sphere: which jobs provide the most pay for each hour worked.
