I disagree. Only the people shown on TV and quoted in the media whine. The vast majority of people do not whine.
What 'hint' are people supposed to get? Every time prices spike, people react. Some by buying a more fuel efficient vehicle. Others by riding public transportation, car pooling, making their own diesel, driving less, or simply adjusting their budget. Do some go back to their old ways? Sure, but it's their choice, but people who make a permanent change, e.g., get a more fuel efficient car, make their own diesel, etc., do not go back to their old ways. Most people have already gotten the 'hint'.
