If you are adversely affected by price changes, then price changes ridiculous, absurd, and ripoffs.

If you are beneficially affected by price changes, then price changes are a result of supply and demand.

The market clearing price has increased, but sellers refuse (or are banned) from increasing their prices. That way leads to queues and shortages.

Of course, in the opposite direction you get inventory piling up (or unemployed people).
