1 - No - would be even less opportunity for young farmers not more.

2 - Maybe but I wouldn't immediately assume yes.  Remember, less ethanol, less distillers, so that corn will be mostly utilized back to animals.  Corn isn't racing back to 2 -sorry.  If it does NOBODY will be able to benefit. 

3 - Fat chance - Because you make an incorrect assumption in #2 you double down on this one.  Way easier to crop than 24-7-365 animal stuff.  Also, an incorrect assumption older generations won't expand. 

4 - How did the livestock guys fair in the ldp days again????

5 - This is the normal business cycle whether one likes it or not.
