I'm a bit about computers and broadband being the province of the rich because old but decent PCs can be picked up along with many other essential items on Freecycle.
Freecycle is an amazing source of second-hand goods which apparently should be denied to people on the poverty line.
Broadband costs us £5 per month as part of a package. I would hazard a guess that the 16p per day rate is far cheaper than dragging your newborn and toddler on the bus to the library every day to look for work. It's certainly much cheaper than a daily local newspaper. Is that considered a total luxury in this day and age? Even if the local jobs are advertised on a certain day there are always plenty of tips regarding up and coming opportunities for people to aspire to.
People in dire circumstances sometimes need to obtain the phone numbers of the companies they are dealing with in order to negotiate with them. I used to do this sort of thing on the office phone and I'm sure many people still do.
When you are a lone parent you are given a premium rate number which kind of puts you off dialling. There is an site called "Say No to 0870" which gives alternative geographical land line numbers for most utility companies. I use it all the time, nor do I ever have to call the hugely expensive 118 118.
Then there are price comparison sites to get the best rate for your insurance, gas and electric amongst other things. My DH saved my Dad £400 per year on his house insurance the other day with a quick tap tap of his phone.
Some peasants have always traditionally wanted to know a bit about what is going on in the world, the cheeky sods, like my Grandfather who fought in WWII, and have always, despite everything, bought a national newspaper!
Now tell me that an internet connection is a luxury. 16p per day, for entertainment, the latest stories and comment, support whatever your need, information including how to budget, keep a clean house, shop well, cook cheap and nutritious meals, find second-hand goods, support for children with SN, all of which can be found right here on Mumsnet.
Bobbins is it a luxury, it's access to local services, communication stamp-free, the availability of completely updated banking and tracking of money in and out, the ability to shop on-line which saves you money for transport, I could go on...
Affluent families might very well not miss internet services because usually they don't NEED them themselves. Why rely on Google maps and BA updates when one's travel agent arranges such details? That is an extreme example but still... it illustrates my point.
