Get rid of the Chicago Board of Trade and the speculators in the market and you won't need gov. payments. As long as the producers can't set the prices they need for their crops, they most likely aren't going to be profitable.
Wrong without the dollars of these city slickers the production channel will be controlled by way too few industrial consumers who in the end would decimate what is left of the small farmers. Soon after your plan went into effect mega corps would move in and farm mega sized farms would be rule and rural people would be in the same boat as 19th century coal miners.
Absolutely!! You wouldn't want the consumers to have any say in the price of crops.
