It is politically incorrect to suggest the supply of unemployed persons slopes up -- that an increase in payments to unemployed people will increase their numbers.
[warning: the laws of supply and demand sometimes reveal themselves in graphic and disgusting ways. You may not want to read what's below -- or see the film. The film is nominated for Oscars, so I assume that most of you already know about it]
Mysteriously, it is political correct -- fantastically popular, in fact -- to suggest that the supply of deformed children slopes up. "...hundreds of young children have had their arms and legs chopped off; scores of others have been blinded. The gangs also pour acid on to the children’s bodies, leaving them with suppurating wounds. A happy ending for the stars of the film Slumdog Millionaire - but for real slum dwellers the future is bleak. Their suffering comes down to one thing: money."
