Before he passed a several years ago, my uncle, Bob Boyer, told me he thought that the candy business would surge. At the time we were in an economic downturn, right after the Internet bubble burst. The thought is that candy is a relatively inexpensive treat during tough times. You don't have the money to do many of the other things you like to do, but you do have spare change to buy a candy bar. Why did he believe this? Because his brother and he started Boyer Brothers during the Great Depression. A nickel candy bar was a treat in a time when treats were in short supply. In other words, candy is a way to get people through tough times.
Granted, the economy then is not as bad as it is today, but his thinking holds true.
If you'd like more proof of this, check out this article - very timely and underlines the point. Plus, I can't help but noticing the subject of the article calls himself a "candy snob." I'm flattered... :)
