Everyone says that you need to save, but it depends on the income of a rich person. If he earns much more than he spends, then he will not have financial problems in the future. You don't have to be very frugal, but you also don't have to spend a lot of money in order not to attract attention.
That is not necessarily true because when you have a higher income, you will also spend on luxuries and more expensive, your money also spends faster so you also need to have a savings plan. even the rich, the billionaires always have their savings in the bank, so it's silly if someone thinks their income is high that they won't have to save. Life is always full of surprises and no one knows what to expect, so never be subjective. saving and always having a backup plan is never superfluous.
