If you knew that you were going to die at 17h00 today, you probably wouldn't bother to go to work; or care too much about making money at all for that matter.
What use is money when you are dead?
Money's real value lies in the future; money and time are intimately linked through the mechanism of interest rates.
Put money in a bank today and that money attracts interest and exponentially grows in value over time.
The human desire to grow wealth is based on a primal urge to secure our long-term future survival, without a future money is largely meaningless.
Money is transactional in the present, but becomes wealth over the long-term.
Now is money, time is wealth.
