The economist always said decent inflation is good for economic growth.

I really doubt with that,it only work presume corporate or business increase earning on raising price of good and service sold will eventually invest on expanding the business hire more worker,increase wages,or extra earning increase spending power of business owner,share holder ending more money pour into market and economic bloom in this cycle.
What actually happen is those corporate sole purpose is make money their not act as roles of disperse inflation into good course like economist state,when too much investment instrument available in market that might provide better return then their core business it encourage them allocate investment portfolio on non-productive assets like properties speculation,stock base executive incentivizing share buy back gain instant massive bonus instead of priortise company growth.Properties real estate and among all other stock market and derivative investment instrument is majority form of medium hoarding all the money supposely to improve goods inovation,labour wellfare.A country where financial market dominate corporate decision making cater more inflation induce wider wealth disparity.Had you seen any billionare who portfolio zero bet on real estate speculation? What is the cause of financial crisis in last few decade? it all come back to either housing or stock bubble that forming by over leverage borrowing to invest on speculate future over investing in physical productivity that fullfill actual consumer need.Money deposit in empty over price rental properties or stock exhange figure dont create jobs opportunity but factory with production line does and farm land cultivate crops feed people.
All of thing consumer can buy these days regarless food,comodities you always get less qty or more inferior quailty over past decade with double even triple fold and feels like the adjustment is way ahead reported inflation from same year mean while the board member and excecutive incomes different between the normal working class is light years away each other.Society is divided into the group of people work hard or involve immensely to produce actual goods and service their asset ir saving get shinking value no matter how hard they work while the actual control the economy manipulate non tangible,non productive financial asset that far way more effective to earning money and using the same massive amount of money to hogging more physical asset from poor.
