Additionally, my assumption is the garbage collection industry is similar to ISPs – meaning options are limited based on location and prices are therefore not as competitive.
Edit: I'd add lack of upward mobility to the first sentence.
This article comes across as if they are getting paid too much for being 'lowly' garbage men. So what if they don't have a degree, It's hard work that is vital for a functioning society and they should be compensated accordingly. Good on them for etching out a living without having to get a degree doing so.
