Re food for thought re paying fees or losing money on bank deposits. (a tax on wealth)
What is possibly evolving is similar to owning a home. (another form of savings) The higher the value of the property, the higher the property tax is.
Some states I hear do a similar thing with car registrations. The higher the value of the car, the higher the annual registration fee. (a tax)
So now, TPTB are saying we need to pay a property tax on our savings accounts, if we are wealthy enough to have one.
