What makes it worth it norris, is the USO. I know you know this so I won't bang that particular drum.
Yes the "junk mail" as we all call it, is in fact massively profitable to the company. It also creates revenue in copious amounts for the companies that pay RM to deliver them. No one is forcing these companies to have them printed and delivered. They do it because it has value to them...end of.
As far as everything going digital...brace yourself! Sunak has already intimated that he wishes to move away from hard currency into digital. Amazingly, his father in law just so happens to own a company that deals specifically with this task! I know right! Seems like that might be a red flag, but no, apparently not.
Before the digital thing, when we used to go into high street banks, in order for someone to empty your account they would really need to be in the branch, not so in the digital world. They don't even need to be in the same country! How many ways would you accept any of your digital information being stolen before you decide that actually, it isn't acceptable? If someone wants to steal my bank statement they'd have to either break into the bank, any of the various steps for sending mail including MC, DO, postvan etc. or they'd have to break into my house. All of those would require being in the same country and being brave or stupid enough to pull it off!
Digital my arse! Sure does make life easier though...If your a criminal.
