Changing 1:1 to 1:100

When you work for an hour, you get an hour's pay... right? The pay-off is 1:1, you put in an hour and get $10 or maybe $100, and it's simple and you go home at the end of a long night and wake up in the morning to do it again.

But let's tip the scale. If I am a teacher and instead of teaching for one hour, I make a dvd for one hour and sell that DVD on line. I could possibly put 1 hour of work, and get paid 100 times, imagining 100 people buy it. 

Which balance seems best to you?
