I'm in except my carpet I badly need new carpet in the lounge
I think this is one of those things where you need to avoid perfection being the enemy of good. If you genuinely need something, buy it. Just buy to last.
Re. retail and jobs, retail is a bit screwed anyway- a recent study showed that the UK high street has about 33% more units than can be supported and needs to diversify into other leisure offerings. I think the economy will evolve. It always has. People will use the money (and time) they save not browsing for and buying multiple 99p vest tops on other things. Demand for other paid leisure activities and the associated kit will increase - camping gear or mountain bikes or gym memberships etc. Buying less may also reverse the trend for fast fashion with people thinking "if I'm going to crack and buy a coat I'll buy something good quality and classic that'll last a few years". However, as a society we also need to balance spend with not living in abject poverty in retirement. We now have about 45 years of work to fund 20 years of retirement. It used to be more like 48-10.
I reflected on this a bit last night and realised that I will still buy a good pair of road shoes and trail runners as needed (every 6 months in my case) but I see those as "good" spends as I get hundreds of hours of free fitness and relaxation out of them. I then donate them to a charity that takes them to Nepal for trekking guides. Definitely don't need any more running clothes and should just churn through what I have till it falls apart or becomes irretrievably stinky. I will still buy books on Kindle (live in a country that doesn't have public libraries and realistically I wouldn't get there anyway due to working FT).
I actually realised that I'm pretty good with clothes, bags and shoes already. I have 2 "main" handbags (one black, one beige) that I've had 3 years each and I predominantly wear Vivo barefoot shoes so only have 2 pairs of shoes and one pair of boots. My work is smart casual so I don't need a specific work wardrobe. My "waste spend" is mainly food and beverage related.
e.g. morning coffees- the coffee from the machine at work is actually nicer but I got in this "treat yo'self" mentality where I was literally buying a coffee that was less nice than the non-bought coffee just to satisfy that "consumer" thing. Now that is whack when you think that I might live to be 90 and if I put that money in a mutual fund it'll mean a lot more to me in retirement than now.
Also, bought lunches, Deliveroo and wine. Gotta stop with that stuff. It's not healthy and it's a waste of cash.
