It always annoys me that business groups are constantly lobbying for increased immigration because of a "lack of supply" of skilled labour. When there is an imbalance in supply and demand with labour we should see an increase in the incomes of those people with the skills in shortage. Instead business groups want to cheat the system and increase supply, not by paying workers more, but instead trying to import more labour, screwing the workers out of their good fortune of being on the right side of the supply and demand equation for a change.
