I think if you're looking to be financially secure in the future, or have certain financial goals to hit, its a necessity. If you Don't have any particular financial goals to hit, its a want.
Personally, I think its a necessity and everyone should have certain financial goals.
It sounds like your firmly believe having some kind of financial goals , and continue to pursue them for achieving them, is essential for financial stability in life. this perspective aligns with opinion of many financial experts who emphasize the need to setting clear objectives and manage finance accordingly. the goals can rage from savings for emergencies , investment and ventures for personnel growth. this can provide direction and motivation, helping individuals to make informed decisions about their money.
Honestly, if you understand the title of the discussion about needs and wants, it has a very close correlation, where in my opinion Investment is a need and wants can be said to be "wants that are needed" or "needs that we want" isn't that the same?
I strongly believe that people who understand finance will really want to invest and investment is a necessity that he needs to take in managing his money, but as I said that this applies only to people who understand finance, and of course he has a target in his life if he has knowledge about finance, so that money management is a way of how someone saves his money in several categories that he needs for now and the future.
