Cash is just so inconvenient. Sure, it’s not so bad when you’re just dealing with notes, but as soon as you add coins it goes downhill fast.
That being said, I do get that cash makes it easier to think twice about purchases as you’re not just tapping your card like it’s a bongo drum.
FPTP is objectively a shitty voting system, up to 49% of the people will go without representation.
I don’t know if that’s necessarily evidence of a decline in U.K. democracy, but it does still make the U.K. a flawed democracy.
