Nowhere did I say luck doesn't play a part. Nowhere did I say I lack compassion for the people in the article. Nowhere did I say that I think things are fine as they are.
The reality of the business world today is that employment is at-will. There's nothing stopping employers doing the things described in this article. So I offered up a way that people I know have managed to improve their career outcomes. Having several consulting clients is often a lower-risk approach to the later stages of your career than depending on one employer for all of your income. This is a forum dedicated to entrepreneurship so I think my comments are appropriate here.
