Then nobody will get promoted as the oldsters continue to hog the top positions causing depressed wages in the prime earning years of Gen X and less opportunity for Gen Y causing the need for even more labor to be imported.
It's not that simple....
Besides, they already upped the retirement age for Gen X.
Why would this cause a need for more labor to be imported?
Would Gen Y stop working or something? If they are not willing to work, neither should they eat.
