Mergers I'd like to see -- Dollar General (DG) and Public Storage (PSA)

Most mergers are driven by the notion, sometimes wildly mistaken, that the combination will bring both a competitive advantage. Some pairs of companies, however, seem so intuitively right for one another, no bottom-line considerations should be allowed to interfere with their matrimony. Like a slot machine and a blue hair with a pocket full of quarters, these two were meant for one another.

George Carlin has a famous rap (NSFW) about Americans and our love of stuff, which drives our need to build more places to put our stuff. That's always struck me as an integrated business plan. Two seemingly perfect partners for such a business are Dollar General (NYSE: DG) and Public Storage (NYSE: PSA).

Dollar General is a leader in recreational shopping for the denominationally challenged. If you have a hankering for neon-colored plastic, something covered in polyester fur, food with the half-life of uranium-235 or clothing with the style of Piltdown Man, DG is your go-to source.There you'll find shelf after shelf of non-essentials, the kind that end up in storage sheds. Currently, the 8,260-store company is in the process of merging with Buck Holdings LP.

If this deal falters, though, how about a merger with Public Storage? PSA (I'm a little uneasy with a company whose stock ticker is the name of a prostate cancer screening test, by the way) is a REIT with direct and indirect interest in over 2,000 self-storage developments in the U.S., containing, I'm sure, a great deal of material from Dollar General. The merger would be an excellent opportunity to double-down on America's seemingly inexhaustible need for more stuff.
