It’s the best financial advice, covid is the marketing keyword to remind you, if you don’t spend every last penny in the wallet, you can never have a chance to spend that again. Spend until you drop you plebs!
You are right that if a person don't spend money when he/she alive then after died he/she can't spend them. But for this if a person spend his/her whole money now then this is one of the foolish decision. Because no one doesn't know that when he/she will die. So spending all the money today by thinking i can died tomorrow is the most bad decision. Also if a father do that then his family members will face so many trouble. So holding money for future is the part of life. But don't be a penny pincher.
