I think the reason, is paper money is worthless. In the old days, what you had in your hand had intrinsic value. If you had a 20 dollar coin, the coin had 20 dollars worth of gold in it.

The best way to get a very Christian country to feel safe with paper money that has no intrinsic value, is to say “in god we trust” on it.

Today it’s meaningless. I don’t care either way if it fell off or stayed on the next design.

gold is worthless the only reason it's worth anything is because people say it is.

So I could give you an 80 lb. gold nugget and you would throw it away because it is worthless?
