but in the last part, you touch lifestyle and I want to remind you that it doesn't apply to individuals that struggle.
minimalism vs frugality
alot of people think to save/invest requires being super frugal, live under a rock like a hermit and never spend. this is not the case
instead develop a minimalist lifestyle.
decide what actually important to your life. what things serve a purpose/function, gives lasting memories.. and spend wisely.
do you need all the clutter of dozens of branded shoes, clothing, household luxuries/decorations.
or can you find the minimalist unbranded options that serve a regular function to only need a couple items
develop it further. do you really need the lavish new luxury car, or just a minimal model that gets you from A to B
do you really need to pay premium transport, carry 5 luggage bags charging extra at airport, containing every item of clothing and gadget your house had. and then sitting in first class on a plane... or can you just put a weeks worth of underwear and shirts/pants into one bag and sit in economy.
frugality of hermit crab living can be a short term aid. but at somepoint going super frugal fails itself because living on "survival" mode too long is a mental break that cant last. the stress of surviving and not living will become its own downfall which usually ends up with people splurging in excess to get that feel good feeling to regain sanity.
so instead be wise about your spending. note wasteful. make purposeful decisions on things that make your life have good long term feelings/memories. and cut out on the wasteful stuff you usually dont care about a week after purchase
When you are from a poor country and try to save some money, you simply have to eat cheap food like rice, buckwheat, bread, potato, pasta, use low-quality oil, etc... You simply have to sacrifice your health for a while which you'll have to pay later. When you are poor, not only luxury cars but even cars don't exist and to save some money, you have to use the bus less, go out less, buy second-hand clothes. When you live in a poor country, you already have to buy shoes that will last you for centuries. So, for people from poor countries, to save some money, you have to be super frugal, live under a rock like you described.
If someone is capable of affording what you described, then that person is rich and probably doesn't really need to save something, that is the lifestyle that poor people want to achieve.
i understand those in poverty, unemployed or poorly paid work cant even afford cars or vacations.. so have less choices.. in regards to minimalism
but as a for instance of minimalism. your family has understood and made the choice that having a cellular device and internet has more long term positives of possible income compared to putting a nicer meal on a plate. no judgement i can understand the merits of such decisions
but even on low income of frugalism, people should still pre-plan the month, before spending on essentials... rather then just unplanned spend on essentials with no money left but plenty of the month left, wondering what happened and what to do
i have visited many countries and seen scenes of what you described, and in many ways far worse
people with what appears to be new sandals, but they purposefully wrapped the soles tread in card or tree bark and used rags as straps to protect the actual sandals from ware and tear. making the sandals last a lifetime, or use plastic shopping bags when wet
i have seen how villages getting free aid rations of rice from charity, killed the market of farming rice.
i have seen how villages getting free aid rations of clothes from charity, killed the market of clothing
i have seen families prepare meals where it says use a cup of rice. and seen the family spoon out a couple spoons from a cup to save a few % to make it stretch out longer. so i am fully aware of super frugalism
yes choices are narrower. but by pre-planning, even that can stretch the money, food to last a few days longer than expected
this is where people then have to get creative about increasing income
and yes increasing income is a different debate which is another category.. separate from the minimalist vs frugal planning concept
when you live in an area where there are buses, where there are shops that sell shoes/clothes. there are opportunities.
heck when you speak with friends and family and speak of the things they wish they could have, even that can be an opportunity. but thats for another category of discussion
