But what is essential? once upon a time we lived in cold uninsulated unheated houses with water from a well and no internal sanitation. CH, indoor plumbing was only for wimps.
Most of us could manage with fewer clothes, but clothes are so cheap, the modern teenager with a room full of clothes has spent less on them than we did in our days of school uniform with two sets of 'civvies' I remember from childhood.
It is expenditure on services that I consider non-essentials. We didn't eat out, once or twice a year at most, made our own packed lunches, did our own decorating, dressmaking, walked our own dogs. Cooked our own meals, no ready meals
Howeve, many people, perforce, had to live without those services during the lockdowns and many, I think, have rather enjoyed it, and while I know many people were out of work during this period, many were simply workng from home or furloughed and the amount of money they have saved as a result has helped many people onto the housing ladder sooner than expected and given others a nice cushion of savings.
