As we investors eagerly read up on the telecommunications and biotechnology industries, there are many other, less exciting, industries we tend to ignore. Bill Mann recently covered one of them as he praised Cemex (NYSE:CX), a cement manufacturer. Here's another oft-ignored niche: socks. It's true that we've covered underwear in general here in Fooldom (see my "South Park" investing lesson of 2001). But like most of the financial media, we keep ignoring socks.

Perhaps we shouldn't. The American sock industry is up in arms about competition with China, fearing that it might unravel in the face of too many inexpensive socks being imported. According to a CBS MarketWatch story, "The Bush administration has decided to consider a request from the domestic sock industry to impose quotas on imports of Chinese-made socks and will make a final decision on the matter just before the November presidential election, the Commerce Department said Wednesday."

It seems that whereas we imported fewer than 12 million pairs of socks from China in 2001, just two years later, in 2003, we imported around 264 million pairs -- that's nearly one pair of socks per pair of feet in America. American sock makers are claiming that the Chinese sock makers are able to price their socks especially low because of subsidies they enjoy and they're therefore making it hard for Americans to compete.

The textile industry overall is a tough business, especially in America. Just ask Warren Buffett, who bought a struggling textile company called Berkshire Hathaway (NYSE:BRK.A, BRK.B) decades ago. Despite having made billions since then with the company as it expanded into everything from insurance to candy to private jets, Buffett has had trouble wringing profits from textiles. (He isn't one to give up, though, having bought Fruit of the Loom a few years ago.) Bill Mann addressed textiles last year, concluding that with production costs so low overseas, it's virtually impossible for American companies to competitively make textiles here.

The CBS MarketWatch article noted that, "In November, the Bush administration capped the growth rate of Chinese lingerie imports on such products as brassieres, nightgowns and knit fabrics." (Economist Alex Tabarrok of George Mason University scratched his head about this as he typed, "there is no domestic bra industry to protect.")

So who actually makes socks in America? Lots of people in Appalachia and the Southeast, among other places. And a bunch of familiar corporations. For starters, there's Sara Lee (NYSE:SLE), a conglomerate that makes everything from cheesecake to Ball Park Franks to Kiwi shoe polish to Hanes-branded socks (and other intimate apparel). There's also Berkshire Hathaway. And there's the privately held 128-year-old Jockey International.

The takeaway for investors is that though we may wish the U.S. textile industry well, we may do best to avoid investing in it. There are more attractive investment propositions elsewhere. And if all this talk about socks makes you wonder where you should sock away your short-term savings, consider these options for your emergency money and other funds.
