I can work remotely with a very basic internet connection. So can others. And you can be a successful developer (in your country, let alone your county) without working remotely.
But on a less anecdotal note, legitimate companies are doing “rural sourcing” of call centers where everyone works remotely and they give you a special boot disk that only runs thier software. They pay better than minimum wage and the requirement is a decent - above DSL internet connection.
But all of them are representated in Mississippi, which (not “rural areas”) is what was being discussed.

Both slow broadband as mentioned upthread, and even moreso low broadband subscription rates as actually covered in the source article, are opportunity-limiting.
