Good question. My gut feeling tells me that it's gonna be hard to make an interesting essay out of this, and that you might run the risk of sounding like you are "whining". You may be right, but positing that "I haven't got promoted but I would have if..." is very hard to do in any objective manner. But what you CAN do (if it helps) is show how you are the best by having survived.... i.e. writing things (in your regular essays) about how "Ina recession where 70% of my company lost their jobs, I was asked to take more and more projects" or things along those lines. That will you TRANSFORM the what-could-be-perceived-as negativity into something positive and good.
