Blowing In The Wind

.
Can someone help a brudda out? These questions have troubled me for most of my life. They might have simple answers, perhaps too simple for my mind.

So, why does a carton of orange juice cost less than the bag of oranges needed to make it yourself? And why is canned corn cheaper than the four ears it takes to fill it?

Why do wood chips and sawdust cost more by weight compared to a nice straight two by four? Aren't the chips just waste from processing the board?

Or, how can a huge public bus bellowing a plume of black smoke to carry it's 36 passengers be greener than 6 smaller cars carrying six passengers each? Or, how can a gigantic diesel locomotive pulling a few commuter cars with 50 passengers each be efficient?

Why does deisel cost more than premium gasoline when it is easier to refine?

And, would the headlights from a plane travelling at the speed of light illuminate another plane in front of it that was also travelling at the speed of light?

For me, the answer my friend, is blowin' in the wind.
