Competition. The availability of competition between firms makes a firm not complacent, and thus become more efficient.

I prove it wrong. As the computer competes for my time with the homework, I ain't being efficient in any sense. Mugging's like the industry that's lost its Comparative Advantage that's never coming back again, yet I can't just freaking get rid of the damned industry.

Bottom line. I'm never going to try studying at home again.
