Where I live in Canada it is the equivalent of about 35 baht per litre.

The playing field is, as you say, the same, its the the rules of engagement (price to consumer) that seem a tad slanted. But when there is no competition, and there is a built in avenue for price fixing, we should not expect less.

I suppose but to me it's no different than a change in weather. Everyone has to deal with it, some manage better than others... if your house and business are in good condition, it's an advantage.

The weather is natures way of putting everyone on equal footing. The price of petrol, profit from same, taxes, their usage, etc, are man made decisions, which require a disproportional share of disposal income from the farmer, working class, transport companies, etc vs the car owner who uses same, for convenience/show of status.

No different from the weather in the sense that if you're prepared for it, it's a non-issue. Like the weather in that everyone has to deal with the same uniform prices.
