That's it! That's it exactly! How do these idiots not see such an essential investment in their own continued economic survival? You don't get industry leaders from a workforce that can't make heads or tails of a contract, can't file reports, can't figure out a shipping label, or needs picture books instead of operating manuals for machinery. Hell, they'd be lucky to be able to fill out a job application properly.
Try to negotiate with potential investors or your foreign competition when you've got a grand total of five employees that can read so much as a motivational poster without them laughing in your face. There would be absolutely no confidence for the former and the latter will eat your business for breakfast.
Can you even imagine how training new hires would be impacted? The added time and expense? If all you care about is a bottom line that right there is reason enough, small business and anywhere with a high turnover will suffer. And man, a proper secretary is going to be hard to come by.
