It depends

If you starts your career when you are young, and those old folks retired or agressive folks left the company. As long as your image has been positive, rarely made any mistakes. Technically good enough, you will have opportunities. ON top of that, the world is chanign fast, company was operating within the rationale strategy, world is flat, changes occur every day, company has a new slogan every year, as long as you have solid and strong technical skill, tactiful interpersonal skill, and not work as a Ostrich, being alerted to opportunities, opportunities will come to you. Of course, if you want to be rich overnight, or want a exciting lfie everyday, go back to China. Here we want a peaceful life.
