License to shampoo
There was recently a debate on this site about the licensing requirements to take pictures of a house in return for compensation. In that thread, I had a little rant about the creeping role of the licensing into all walks of our economic lives to the detriment of our nation as a whole.
Here's a link to an article in the WSJ on this very subject.

It appears that the proportion of the workforce that is in "licensed" jobs has been steadily going up for several decades. It used to be less than 5% of the workforce half a century back, and has now reached 20% of the workforce. No wonder some people think that one would need a license to tak pics of a house.
