Is there a shortage of cruise ships? Perhaps cruise ships require many man hours and not-abundant resources to make. Perhaps software engineers require many man hours to make and intelligent people with a passion for computer science is a scarce resource.

We can say "there is a food shortage" because a certain amount of food is necessary for a society to survive. The same can't be said of software developers.

Also, if you argue a high price means it is scarce, does that mean there is a shortage of hedge fund managers and CEOs?

Which explains the critical shortage of Ferraris in my driveway.
