Lyrics from Woody Guthrie Songs After He Went Commercial

They say a Tycoon / Hits Like a Typhoon
But Brother That's the Bunk
Every Millionaire / Has Treated Me Square
It's the Poor That Have Always Stunk

This land is my land
It is not your land
I have a shotgun
You do not

From Wikipedia:

"Grand Coulee Dam" is an American folk song recorded in 1941 by Woody Guthrie. He wrote it during a brief period when he was commissioned by the Bonneville Power Administration to write songs as part of a documentary film project about the dam and related projects.

The song was part of the Columbia River Ballads, a set of 26 songs written by Guthrie as part of a commission by the BPA, the federal agency created to sell and distribute power from the river's federal hydroelectric facilities, in particular the Bonneville Dam and Grand Coulee Dam. On the recommendation of Alan Lomax, the BPA hired Guthrie to write a set of propaganda songs about the federal projects to gain support for federal regulation of hydroelectricity.

Neanderthal, when I was wee the lyric went "I've got a shotgun / You haven't got one."

IIRC

I've got a shotgun / you haven't got one
If you don't get off / I'll blow your head off
This land was made for me myself
