If you are getting labour at a cheaper cost, then there is high probability of getting not skilled people on board and thereby IMO creating a group of void professionals. This void is due to the increase in the demand for labour but since companies want to increase their revenues they rely on cheap labour at a small price to them. But on a longer run I think this void from multiple companies will act detrimental to the economy due to the inability of this group to look for alternative jobs when there is a state of economic slowdown.
