Yes, it's possible, but it doesn't apply in every single case. It bothers me too, when old timers refuse to retire as if they're gonna live for ever. But sooner or later they have to retire, and people move up. And not every job can be filled with an unskilled laborer from another country. Where I work, for example, applicants must pass tests, go through long training periods, and have union seniority. Yes, I support the union I am a member of. This is where I disagree with the right, because unions balance the power a little, hopefully in favor of the worker, so that the employer doesn't shit all over the workers every chance they get. When it comes to money, checks and balances are the best things we have to try and maintain some fairness. However, do not assume that I am suddenly now a socialist.
