Prices can't rise and stay risen unless there's more money. Full stop.
A Missouri State economics professor ran the thought experiment in a Money and Banking lecture , and it flips how most people picture inflation
Imagine every seller in the country raises prices 10% tomorrow. Bread , cars , newspapers , all of it up 10%
Where do you get the extra money to pay?
You don't. Your paycheck didn't change. Neither did anyone else's. So you buy less. The sellers who raised prices watch sales fall and quietly walk them back down.
No new money means no lasting inflation . You just get a wave of price hikes , then bankruptcies , then clearance sales.
Now add money. The Fed increases the supply. You've got 10% more in your pocket, so does everyone else. Now when sellers raise prices 10%, you can still afford your usual cart. The higher prices stick.
That's inflation. It only runs with fuel in the tank.
The professor's timeline: money supply rises today, jobs appear in about six months, and the price increases surface a year to two years later.
So when the headlines say prices are climbing and nobody can explain why, look back eighteen months. The cause already happened.
The price hike is free to announce. It only sticks when the money shows up to pay it
Both run about 250 words. Want me to push one harder on the Fed timeline, or tighten either for a shorter scroll?
