You can have price increases without inflation.

For example, let's say the only things you spend money on are eggs and gas. One day, the price of eggs goes up. You buy eggs, now you have less money to spend on gas. The demand for gas goes down, and so does its price.

I.e. a rise in the price of eggs does not result in an increase in your income to cover it.

But with money creation, there is more money chasing the same goods, so your income goes up along with the prices.

It's the Law of Supply and Demand in action.

But... When the cost of gas goes up, so does the cost of almost everything else because the trucks and trains and planes that deliver everything all use gas of some kind.

Supply and Demand still applies. If you have less money, demand drops, and so do prices.

Not for food or energy. Those are pretty necessary and it's hard for people to consume less.
