> The same goes for home internet - the cheapest non-promotional rate in my area is $45/mo for 10mbps, but pay $20/more and you get 100mbps. Why isn't there a sub-$30/mo offering?

I know that Cox has some kind of "low speed, low price" offering, that I believe is under $30/month - but they kinda hide it on their site; I think you have to explicitly call and ask for it. See here (scroll near the bottom):

Note the "Starter Package", then note the package one level up ("Essential"). If you click on the link next to the "Starter Package" for pricing, you will be taken to another page - where the lowest shown tier is for the "Essential Package". But I'm pretty sure you can get the "Starter Package" if you call first.

There's also this for low-income families:
