It's easy to prove you wrong because you made such a blanket outlandish statement...
Money is the LEAST important thing?
A used piece of toilet paper is less important than money
A tiny scrap of unusable Styrofoam is less important than money
a single follicle of discarded dog hair is less important than money
etc. etc. etc.
all are "things" and all are less important than money. If I had a penny in one hand and any of the others in my other hand and told you to choose one, you would probably go with the penny
However, if you are saying money is NOT the most important thing... well then yes. Time is more important than money (I still don't know why we exchange time for money in such little amounts

) your health is more important than money, the ability to use caution, rationale, logic, imagination, and intuition are all more important than money etc. etc. etc.... but money is not "the least important thing"
now rep a breh for seamlessly proving you wrong
