Kids these days will never understand the value of money

Nor should they, because the folding stuff is disappearing into phones and cards

Where's all the money gone? I don't mean why it's flowing out of your bank account in ever greater volumes. Actually, I do mean that, but in the most immediate, tangible way. Not very long ago, you knew what you spent because you could count the banknotes as you handed them over. Money was physical, tangible, and real. That's less true today."
