Yeah. If their fuel costs were $1 and their profit is $1 million, a 68% increase in fuel cost makes no difference.
It's like the food companies in Canada that defend their price gouging by claiming their profit margins haven't changed. It's true, but if revenue is 2x what it was last year, the rich families that own those businesses are getting 2x the profit while trying to blame higher costs for the increased prices the average person is seeing.
I said if revenue was 2x with the profit margin being the same, the profits would be double. If your margin is 20%, would you rather have $10 in revenue ($2 profit) or $20 in revenue ($4 profit)?
So if their costs go up 20%, they increase prices by 20% to compensate, and they maintain the same margin, the profits are higher.
