I can understand what you're saying, but there's a different way to look at it. Imagine yourself in the future. You're in a position of leadership and people want your advice. Let's say a student asks you how they should get a high level job in a competitive marketplace. What would you say?
Personally, I would tell the student they should be ambitious and tell people what their skills are. They should ask for responsibilities and compensation. They should tell people that they are worth the risk.
If you agree with me about giving that advice, then you should now put yourself in the place of the student. Shouldn't you receive the same advice? Shouldn't you be ambitious and ask people to give you responsibilities and compensation? If so, then you can understand why selling yourself is actually important and there's nothing immoral or slimy about it. It feels wrong sometimes, but that feeling may not be aligned with reality.
