A few companies are working on how to ID people who are vaccinated, getting rid of cash entirely etc.

My dad was right. Getting rid of cash
The only way to combat this is to get your money up ASAP and travel someplace that isn't as "first world" (but safe).
A lot of passive income or a way to make money without leaving the house ideally.
You might not even be able to fly without being vaccinated. So you better have enough for a private jet ride or go dutch.
Would be interesting to see if Gates get the vaccine(barcode).
