Well, not exactly that simple.
You see, the DuPonts had made their fortune growing cotton with slave labor. Cotton requires fertilizer, pesticides, herbicides, naturecides, (ok, i made that last one up

), so you see how the giant DuPont Chemical became a viable market force...
America having the best government money can buy, passed a "Tax Stamp" act on it because the Medical Comitteee of congress wouldn't go on record saying it was as dangerous as Mr. Hearst was making millions saying it was. His style was branded "Yellow Journalism" (think "Tabloid", only with a racist bent) Negroes under the influence of Demon Marijuana would dare to "step on a white man's shadow" and "hopped-up darky's" were known to laugh when a white man told them to go to the back of the bus. It's all public information. Jack Herer has extensive footnotes.
Anyway, Hearst had an axe to grind that would gratify his racism because Zappata had nationalized 800,000 acres of Mexican timber that Hearst had bought to turn into newspaper pulp. The DuPont laboratory had just perfected a sulphuric acid process to more cheaply turn wood into pulp for processing into paper (think acid rain) & the only competition for their cotton was Hemp.
If I remember correctly, a DuPont girl married a Hearst-friendly bankster and they managed to pass the first bill that by-passed all congressional committes going directly to the Ways & Means Commmittee on which the bankster himself, or the congressman they all bought, sat (It's been a long time since I read the book).
So now, no doubt some of those gov. boys are benefitting from the cash flow that violent criminals are enjoying.
