From one of my fave bloggers...

Let's revisit two young MIT graduates. Back in 2005 I found them
sharing an apartment. My student was earning $90,000 per year working
80 hours per week on a new videogame. His classmate was selling
$750,00 mortgages to people with bad credit, earning $150,000 per year
working six hours per day

I figured that this couldn't last forever. A society could not
continue bestowing most of its economic rewards on those citizens who
contributed the least to sustainable GDP growth. I thought that surely
the pendulum would swing back and the engineer would be reaping much
more in the way of rewards than the mortgage fee collector.

What's the story in 2008? The mortgage gig came to an end and our
young genius is now in law school, preparing to join his fellow
lawyers in reducing GDP. What about our diligent engineer?  Laid off
when the project ran over budget and got canceled. He's looking for
work.
