I totally agree with you, just saving will not help us have a prosperous life because of inflation, prices increase yearly, and the currency depreciates, so saving has no effect anymore. Instead, we should invest and accumulate in deflationary assets like gold, real estate, or bitcoin. Only in this way can we deal with the fact that goods are increasing day by day due to inflation. But saving should take precedence over investment, I mean we should have a savings for life before thinking of investment because investment also has certain risks.
A lot o people who work do not believe in the idea of investing. They believe they can just save for the rainy day or save for retirement.
With the rate at which inflation is increasing, it is really not advisable to just save. I know everybody needs savings, but a part of that savings we're making should be used for investments.
Investment is risky, it is simpler to just save the money, but if we always go for the simpler options we will never get what want.
Investing can never be overestimated. Without investment we can never attain financial freedom. No matter how much you make frome the job you do, you need to invest in other for you to grow.
