No one can deny that there are quite a lot of benefits that can be felt by saving at a young age, but what we also have to realize is that not everyone has the opportunity to do that at a young age, perhaps due to environmental influences or inadequate income.
So we shouldn't just focus on that, we can still do many things even if we don't have savings, the most important thing is knowledge, in my opinion it is a big capital in life.
If you want to enjoy your old age you can't always do it by saving, in fact I think a good plan for enjoying your old age is by investing.
And how can you invest without any savings? Saving any disposable income you may have is the first step before you can become an investor, and while without a doubt knowledge is important, it means nothing without the money necessary to take advantage of it.
Besides once you read several books about investing, there is not much you can learn from them, and instead you need to learn by actually using your money to buy the assets you like, and in order to do this once again you need money.
