The most expensive commodity is: time.
Inflation growing at a faster pace than wages places the average worker further behind via declining standard of living. The greater number of distractions society faces from social media and other time wasting / time draining content can make it more difficult to focus on goals. It becomes harder to differentiate between what is important and what is not.
Basic necessities like healthcare, higher education, homes and student loans becoming more expensive generally implies greater quantities of time are required to afford these things. Rent, food and basic living prices are also inflating which implies less time.
Many people need to work 2 or 3 jobs to make ends meet. This leaves them with little or no time to devote to other things. Having the time to pursue hobbies, side hustles, personal interests. Or even having the time to spend with love ones, family or people you care about. These things are increasingly becoming a luxury. And so I'll go out on a limbe and say time is the most expensive commodity. And possibly also one of the more key commodities which will determine success/failure in a person attempting to attain financial freedom, start their own business, become their own boss, get a college degree or otherwise invest in things which could dramatically affect the quality of their life for the better.
I fully support you. Indeed, have you ever thought how much time we have to live?Why does everyone cling to gold, silver and other inanimate goods,when the only product that can not be bought is our time,which everyone does not have so much.Take a look at this picture and maybe one of you will think about what is really valuable.
