When we use cash we bypass the banking system. Just think about it. Even if everyone spent 50% of everything they purchased with cash how powerful that would be. My guess is folks spend 20% or less of everything they buy with cash. We live in a society where we are rewarded when we use credit and debit cards. We get more credit and kickback and cashback which is how we are trained to become a literal cashless society.
Costco rewards folks greatly for using their ‘credit card’.
Friends keep cash on hand. Keep coins on hand and silver and gold. Urge your friend to pay in cash as much as possible as well. We all need to be very aware of this and plan accordingly. It doesn’t take that much more effort to pay in cash.
