That is what most people don't get. You work for your retirement, not only your salary. Delayed gratification is hard, but it pays off.
When we are productive then we have to force ourselves to be able to save and prepare for retirement, calculate the needs if when we retire with our wife then we have to do it right away, the other most important thing of course is preparing an investment or business that will be a source of income when we are old.
It is better to save for old age security because at that time a person becomes unemployed. If you save for the future, you don't have to be dependent on someone in old age. You can use everything as you wish. Usually parents are dependent on their children in old age. Parents are affected by various complex diseases in old age. If the policy makers are not alerted in advance to change this situation, there will be adverse reactions in their lives in the future.
