Prices go up and prices go down. Demand fluctuates.
But people have only so much to spend.
If a bunch of people suddenly decide they want more of X, demand for X rises, and the price of X goes up.
But simultaneously people buy less of Y, demand for Y decreases, and the price of Y goes down.
That’s the way markets work, except...
If the price of everything goes up, it’s not demand that’s driving it, it’s money supply.
Exactly right. Inflation is the GENERAL movement of all prices, not supply & demand fluctuations of specific products or services. They are different.
