I think I can see what you’re getting at OP. It would be great if minimum wage, or even average wage, could support housing, utilities, food, clothing and other modern- day essentials (broadband, mobile phones, home entertainment Etc.)
However, while utility, mobile phone/broadband and home entertainment companies are allowed to continuously charge obscene amounts more than it costs to maintain the networks and supply, I don’t think this is likely to happen.
If we go back to the early 1980’s, a normal quarterly phone bill would cost maximum £5.00 - fast-forward to today, and in a household with 4 mobile phone users, we are looking at a cost of £100.00 per month!
Add that to the trend of buying stuff for home use, then having to subscribe to use it (Peloton, I’m looking at you!) I can’t but feel that other manufacturers are going to jump onto this bandwagon soon, and you’ll either no longer be able to buy your appliances, or you’ll have to subscribe to the manufacturers to keep them working.
This is the new model - do you think a single average income could sustain that against such temptation for manufacturers to make so much more regular income?
I laugh at your idea of 'modern-day' essentials. With the exception of broadband they are really NOT.
No-one has to subscribe to anything that feeds into a company's profits.
Just live simply

If minimum wage was raised - inflation would be let loose. There would be cries for more benefits and if people took years out to 'find themselves' and were still paid by the government (aka the taxpayer) - where would the money come from?
I am a single person household on circa £13k p a (NOT one of the 'rich pensioners' ) and I have to find council tax, utilities, broadband and phone, PAYG phone (quite sufficient), insurance, keeping the car on the road (18 years old now) and saving a bit to replace broken goods. I get most of my furnishings second-hand, ditto my clothes.
Forgot the cost of the dog to keep me sane.

I appreciate that many of you see getting generous maternity pay, working part time for full-time wages as very desireable for yourselves but it all has to be paid for.
