Wealthy farmers destroyed crops that weren't worth the money to sell, yes, and poor farmers went under. That's not a surprising idea, given that it continues to happen in our modern farming system all the time during periods of overproduction.
>I'm not obligated to find a proof against fiction
But you might be compelled to give some counterproof to Steinbeck's non-fiction reporting, which was also linked above.
All first hand accounts of the dust bowl talk about sandstorms bringing sand, everything getting burried in sand. No first hand accounts seem to talk about fields getting stripped of soil, that was documented after the fact. This suggests that the source of the dust were fields that had been abandoned.
It doesn't even make sense, Oklahoma isn't dry, the American south is very humid.
Sure you can. Food supply is not just a question of production, you also need logistics and will to distribute. There is currently a global food surplus, but areas of the world are still undergoing famine.
>in fact food prices were dropping
Up to 1931. If you look at the data into the actual Dust Bowl years, 1932 to 1936, prices go back up significantly.

But the Dust Bowl occurred in an extended drought period when Oklahoma was incredibly dry. And while it's true that topsoil was lost from fields that weren't farmed, those fields were fallow because of the drought - crops couldn't be grown in the dry conditions.
The fields were abandoned because the prices were so low that cultivating them wasn't profitable. This in fact could have caused the drought as well, as much of the rain in such climates is recycled - the water that evaporated rains back down. And, it can't evaporate well without plants to bring it up from the soil, but only the surface dries out. This might have lead to the dried out top layes getting repeatedly blown away, until the fields got successfully overgrown, and the rains returned.
