Industry or: How a term gets increasingly misused …

Quote from the German ARD television program’s website on 14 May 2008: “The President of the Federal Republic of Germany heavily attacked, in an interview, the international finance industry...”

Did he really say so, or is it the wording of a journalist?

Elsewhere terms are used like tourism industry, test and certification industry, cleaning industry, software industry etc.. The term “industry” originates from Latin where “industria” means “hard work”. But that shouldn’t be a reason for using “industry” as an appendix wherever hard work is performed, or get other branches envious on the productivity and the many workplaces of industry? Typically, “industry” is characterized by factories where tangible goods are produced, like cars.

Should the well known “services” have experienced, in recent years, such a decrease in appreciation that they want to decorate themselves with the word “industry”, or do we see simply a sloppy use of language?

A more correct use of terms would be finance, test and certification services, cleaning or cleaning services, and the software branch.

It would be regrettable if the languages‘ options for differentiation came out of use just because the over-generalizing „industry“ affords less thinking.
