Why is money so important in life?

All life we run after money but when we die we take nothing with us than why is money so important. Why can't we draw a line and say this is enough for a peaceful life and just forget about everything else and live life king size. 24x7 most people run after money and forget to live life, they forget their family, friends, everything and eventually when you need someone by your side you feel all alone.

Why do people forget that money can't give you happiness. It can give you peace of mind. All it can give you is materialistic goods but real happiness you need to look beyond money.
