So you want US currency to look like other countries funny money?
Since the Euro, the Canadian dollar and the Yen (among other currencies) are increasing in value while the USD is decreasing, calling them “funny money” amounts to throwing stones in a glass house.
No. But I want them to be as hard as possible to counterfeit. As it stands right now, North Korea and Iran (among others) are counterfeiting US money to prop up their economies and hurt us.
Personally, I think that is an act of war, and should be dealt with the appropriate fashion, but, until then, we need to make currency as difficult as possible to counterfeit.
