all right bitches I'm here to teach you econ 101. THe article starts with the words "Hiring good help is never easy, but the difficulty is compounded considerably when demand for the skills you're seeking exceeds supply." Economically, the expression "demand exceeds supply" is meaningless: you must say, demand at a given price exceeds supply at that price. Now there are a few different supply curves, some of which are more "responsive" to price than others. Take something scarcle, like $2 bills. Would you say "demand exceeds supply"? Again, depends on the price. I guaran-damn-T you that Demand for $2 bills at a price of $1.90 far exceeds supply. After all, if I didn't have to do it in one batch, my PERSONAL demand for $2 bills at a price of $1.98 exceeds the entire world supply of $2 bills. That's because I can immediately use the $2 bill to get $2 of currency.
Developers are similar. It's not that the supply of developers doesn't respond to people who want to pay $500,000 or $1,000,000 for one (as is the case with Rembrandts or Picassos). Instead, someone wants to USE a developer to create a $500,000 or $1,000,000 company, while maintaining majority ownership. So, in this sense, the supply of developers falls short of demand in the same way that the supply of $2 bill falls short of the demand for it -- at $1.50. It does not fall short at even $3.
But there is a supply of $2 bills for which supply EXCEEDS demand at $1.50: novelty bills created by me and having no value. I will sell you my personal design of a non-legal-tender $2 joke "bill"... for $1 each. How many do you want? My personal supply at that price is in the range of about 100,000 pieces immediately, which is what I can produce off-hand in a hurry. How much is the global demand for my "bills" at that price? 0.
Developers are the same. What is the global supply of developers (anyone who can code at all) at $100,000, $80,000, $50,000 or even $17,000? HUGE. The problem is that these are not the same developers who will make you a $500,000 or $1,000,000 company.
