populations grow first and naturally so
this then causes demand which needs a supply to meet demand (even before productivity)
good inflation would stay at 2% IF money printing matched population growth and its economic productivity rate
That would justify circulating supply but NOT the inflation. Inflation happens when there is more supply (of fiat) than demand and it only happens when they print more money than they should. Otherwise population growth is only a small contributing factor to the demand for more fiat in circulation (still not for inflation).
nooo
your getting your chickens and eggs in the wrong order..
look at the topic question
i gave an example of it being necessary(when its controlled)
the separate question of excessive inflation is when its not necessary(not helpful, not beneficial, not needed)
the printing of money does not happen at the same time as the population growth so there is always an over supply of money before it trickles out to the population need. and peoples needs expand as technology and products get invented. so the amount of money needed expands
(its cyclical)
in a controlled system these increases would be small. .. but still necessary
EG markets will compete for peoples money and markets then need to pay people for the work so they can then spend to consume those products
(everyone always want more in the fiat system)
(chicken)
EG a couple about to have a kid know their household income would need to increase so they need a pay rise. getting a pay rise incurs extra costs on their employer.. which means although parent is less productive than their younger selves(age slows people down) their income:productivity rate changes where they need more income for less production
so their employer needs to raise price of goods before the families child grows up to become an independent productive member of society, earning their own income and consuming from that separate from the parent,
so for many years of adolescence. the parents will need more income for each parent. meaning each parents employer will need to pay each parent more which means the price of goods goes up but the productivity does not
and with more money needed in these child developing years(population growth) there is a need for more money in society until the child becomes a productive member of society to then circulate the money increase to stabilise the inflation..
but with that years later(egg)
EG the amount of money a young single adult needs to live on whilst living in parents house with no kids of their own is less for the young adults than the amount a middle-aged parents needs who has a family where parents income needs to be higher to cater to his growing family,
by which time the cycle starts again with the young adult then starting a family
do you now see the whole picture...
yes in a different universe that was not FIAT based.. inflation is not needed and we would live in a deflationary system where each year our average savings/income would be worth more produce per unit, so would spend less units per product..
but the reality of the real world we actually live in, of the real world systems of fiat which does exist outside of our dreams/outside the crypto communities.. inflation is needed to keep the fiat system running.
we as individuals do not own the fiat system, we are the slaves to it. but its the system that is most active amongst populations so we have to admit its existence and relevance to the greater population utility
we may not like being slaves to the fiat system, hence things like bitcoin are an genius asset that was created for those who want something better. but bitcoin is not the system used by the legal systems and government of the lands we live on
and in the world of admitting fiat exists and is used by the majority, that fiat system needs inflation to operate. however the amount of inflation can change from good(necessary) to bad depending on the amount of inflation
the fiat system would crash if it was 0% inflation and humans would notice financial issues affecting their lives if it was 0%
