The fight for height

Remember the silos from before
I can see them outside my door
They store the grain and maybe seed
But elevation is what we need
I see them rise, everywhere
But they just don't surge
Like the one in the 'Burg
All of the farmers in the land (egos abound)
Want the tallest silos in demand (all around)
When it is all said & done
There is only but one
They can try to make theirs high
But the grain elevator
Can't be denied
