Maybe December? So we all take money out of banks, at least current month salary, and spend cash only. I think that is something that shouldn’t be hard to do and it would show if we, the people, have any power left to make positive changes for the future or we can just surrender and eat bugs.
Edit:
If I’m trading my only true value, my time, then I want to have 100% control over it, not to depend if some bank would freeze my account and I lost 1/3 of my life irreversible.
Maybe I’m old-school, but every paycheck I take out a few hundred to act as my spending money. I mostly frequent small businesses and I know they prefer cash to avoid fees (and possibly taxes but that’s none of my business). It also helps with budgeting.
