People - how do you think that meat gets to Disney World? How do you think anything gets to Disney World? By truck. And trucks use fuel. And fuel prices have climbed how high in the past year? Even if the trailers are put onto trains, you still have to get that truck to the train and then unload it and then get it to its destination.
Anything you eat, unless you raise it and take care of it yourself, has to come by truck. That will be the last place your groceries are put before it reaches your marketer's shelf. Or goes to a restaurant.
So, fuel prices go up, trucking companies need to raise their prices, supermarkets have to raise their prices, restaurants have to raise their prices.
It's not about greed or supply and demand or whatever. Go back to the source and think about it.
