Do your neighbors who don't buy fuel buy any goods which were transported? If so, they buy fuel.
Holy smokes, what an amazingly helpless attitude!
They don't buy goods that are transported, they grow their own food, make their own clothes out of what they can scrounge and when they travel they ride horses. They cook on wood that they've gathered.
Bear in mind that this is not some kind of goofy 'back-to-nature' shtick, this is how hey live. Those that can will grow some cane, mill it, and sell it to get cash so they can buy fuel. Fuel is bought by anyone that is able to, but those that can't don't just roll over and whine like whimpering helpless ninnies. It's them that has money that's got the choice, and it's those that don't have a choice that doesn't buy fuel.
Americans don't have to buy fuel if they don't want to. They do because they can.
using your logic we're forced to buy all kinds of stuff. The trucking industry is fueled more by coffee than it is by gas (shipping trucks mostly burn deisel, but truckers pound coffee like normal people breath), and everybody knows that to make a better cup of coffee you need better water, which means bottled water, so with your "trickle down purchase" concept we're "forced" to buy coffee and bottled water.
