FDR did not steal all the pigs, he was slaughtering some of them so that the farmers would be able to afford them, and also so that the economy can get back on track from hoovers mistakes. The pigs would take up pig farmer's money so they could buy food. This would raise pig prices so the farmers, WHO WERE HIT THE HARDEST, would have money to support themselves, as too many pigs means that pork prices would be dirt cheap. And if you believe that this caused big prices to raise to a price most people could not afford, then your wrong. The new deal provided many, many jobs for unemployed people, as provided money to most. The only problem was government deficit, but it was necessary with the great depression so far in and it not fixing without drastic means of saving it.
