In 14 years, the only folks still using cash would be those people who participate in the black market.
Bingo.
Paper money for the paper people.
Cash in 2030 will be like stamps in 2016 except that cash will probably be illegal to own and use and like gun ownership and Bible quoting, using any of these things will get you labeled a rightwing gun loving Jesus freak nutjob..in other words,you’ll be put on the Conservative domestic terrorist list— “no soup for you!”
“black market”....that’s raciss!
