Money acts on specific dopamine receptors( i believe the same as which causes primates to wish to horde items.. don't quote me on this) . So it is possible to develop a sense of positive reinforcement (ie accomplished after paying bills or a treat or whatever) with the idea of god.

Have not thought about it. certainly possible.

I will have to try and find some more to support this idea...

All US card readers are now moving to card chips instead of swipes. We'll all be microchipped soon enough...like my cat.
"In God We Trust" was only added to cash during the Cold War for red-baiting.

"In God We Trust" was added in the 1950's as a counter to godless communism. Congress also added the phrase "under god" into the pledge of allegiance at the same time. Ironically it comes right after the word "indivisible." Cards don't have them because corporations don't care. Why would a bank pay more to print "In God We Trust" when I can pay less and maximize my profit margin, while not alienating potential customers?

As an Australian, I find US currency both bizarre and amusing. The invocation of god on the currency is, to me, anachronistic. Also, that US cash is printed on paper. Australian currency is made with polymer, which makes it both more hard wearing and much harder to counterfeit.

I understand that the US Treasury would love to move to polymer, but the US public would never accept that.

All christians really worry about is their denomination.

Pun definitely intended.

I really don't think so.

Plastic has been around for so long is becoming out dated. Now it is just a number in a data base. That that is, is still here. IDK the future.

Yeah, that should put an end to monotheism pretty quickly. I suspect theism will end a couple days after.
