“cashless” will be implemented, not “happen”. And sooner rather than later if enough people help set it up...hint hint
You are missing a key aspect of society that is “cash only”.
The USA is not going there.
The IRS would love it but it isn’t going to happen.
Those that can pay off that card every month will get rewards. That is the benefit.
Many in the USA do not use credit cards at all.
If you think past riots over some lawful miscarriage of justice was wild, try taking away cash. All cities will burn.
