@thor you certainly arent wrong that spending on things that make you mentally healthy and happy are neccesary too.. Im not claiming you shouldnt be spending on anything... My only point is, cutting back on those small every day expenses absolutely is a mentality and practice needed to get out of poverty.
small every day expenses
There's the issue that often buying in bulk (or larger sizes in general) can be cheaper in the longer term.
It's one of the traps of poverty, with the stupid example being that one could buy a 500g box of cookies that last him a week for 10€, or a 1Kg box for 17€ that lasts him twice that.
Optimizing for the short term is suboptimal
While your right, the whole buying in bulk could be a potential trap of poverty.. its not really a good excuse... I dont know too many who got out of poverty by buying in bulk.. i mean yea sure once your able it might be an ok move to save a few pennies... but its not nearly as important as just penny pinching.
Oh I absolutely have an ideology (as do you)... You are speaking of opinion and ideology whereas im speaking from a lifetime of actually helping people get out of poverty and seeing what does and what doesnt work... yes its math, and buying in bulk, while helpful, is not a requirement to get there.
