With a single print ($100) they recovered the costs of the entire labor ($100, or 10,000 cents). This is a great metaphor of our modern production chain, isn't it? (i. e.: How production exploits cheap labor)
I'm pretty sure the average Mechanical Turk user could have scraped together $100, if they'd thought of it.
If you're going to talk about Big Capitalism exploiting the cowering, puny forces of labor, you might want to pick a business where the startup cost is in the low three figures.
